Excellent against Hunter, Aggro Warrior, etc. Simple, efficient, that's all, folks! Balanced against Arcane Explosion and Powershot, but not Maelstrom Portal because everybody knows that the powercreep is real.

A pretty basic single-target buff spell, more or less quintessential in all classes. Balanced against Power Word: Shield, Sunfury Protector and Mark of Nature. However, I did not create a buff like this for the hell of it. Zanywoop reminded me that this class will have several slow, huge minions. What better way than to get some quick use out of them than to give them Taunt?

Aight, so this is one of Spiritwalker's solutions to big threats. Based off of Sap, it can either be a worse Sap, or a far better one. As is obvious, it will mess up your opponent's next draw, but if it's late game, they can just slap down the same minion next turn, so you'll need to be careful with this.
Also, it's not an actual retreat. A spiritual retreat is when you go somewhere far away to think about the meaning of life.

Hammer of Wrath's big brother. Starfire's younger sister. What?

A simple minion, perhaps, but the stat distribution is excellent. This class want to have large, protective minions. Something as basic as this serves that role nicely.

Excellent in the control matchup, slightly risky in the aggro matchup. You cannot topdeck this card. Period. Ironically, you can't rely on faith for this spell to work. XD

So yeah. The class banner said strong draw power. Sure, it's weak but the draw two is amazing when slapped on a minion. You're getting 4.5 worth of mana, at any rate.

I find this card to be the most interesting and my favourite of the Basic set. An excellent early game minion-spell. This just goes to show how far the Spiritwalker class is able to take the "at the start of your turn" and delaying mechanics.

Annnnd here's the big spell. This could potentially support Token Spiritwalker. You would build up a board, and after playing this, force your opponent to trade into everything. This card is a bit one-sided, but it's essentially just a slower Bloodlust or Savage Roar. In fact, it gives your opponent one extra turn to react. Perhaps 7 mana is too high?

You had best believe there will be future interaction with this card! A close second to my favourite card in this set. Though a pretty simple card, there is so much room for future development for 'Gather Your Mind' decks.

An interesting healing card, though rather niche. In most cases, it will heal about 4 or 5 damage, so it's about on par with Flash Heal, as Flash Heal does not have any requirements to use.

Here's the second card in the "Gathering" archetype. Very self explanatory, and a combo-oriented card. Though you are quite literally giving up one mana, when you draw into a Gather Your Mind, you'll soon have a ton of hand advantage.

And here is Spiritwalker's only 1-mana minion. One of the infamous 1-mana 1/3's. However, it doesn't increase its stats in any way! Wow! Who woulda thunk?
Stray Spirit acts as an introduction to the Immune mechanic, an obscure and rather complex keyword. By having Immune only on your turn, the Spiritwalker player will learn that you will not take damage when trading, and you can target your own minions with effects, so, perhaps, an Abusive Sergeant buff.

The other side of the coin to Thunderwalk. I find this card to be much more useful than Thunderwalk as he provides a small body on board while still giving hand advantage. I was on the fence about having the Tenderhoof as 2/3, 3/2, or even 2/2.

Giant Thunder Lizards are seen roaming the Emerald Dream. The Spiritwalker's probably dreaming about them or something, and envisioned it stepping on his opponent.
In any case, this is our first look at Slumber. This is the most obvious application of Slumber, to put it on a humongous minion with over-the-top stats. Essentially, this is an 8-mana minion, but, you get the body on board earlier, allowing you to taunt it up, or, if need be, trigger its deathrattle.

By itself, this is just a weaker Demolisher. Once you start adding draw power, however, it can become as deadly as Knife Juggler. I think this should be a 1/3, though that does seem too weak. 0/4 seemed to passive, as well.
In addition, this is why I had a few of my cards in the common worded as "adding a card to your hand", so they would NOT trigger this card's effect.

So it's sort of the opposite of Far Sight? Hindsight obviously works best if you copy a card you draw without using your Hero Power so you know exactly which card you are copying. Therefore, you need to be rather careful with this. 

WIP

This card was very difficult to balance. However, it does allow for a good amount of counterplay from you and your opponent. If you play this card in a fast deck, then your opponent will waste the immunity on a weaker minion. The best use for this minion is to protect a large minion; Your opponent will be forced to trade into this 4/4 body first.

A rather curious draw/cycle card. You instantly draw a card for just 1 mana, making this the most mana-efficient drawing card in the game, but you mess up your next draw. Of course, you can just use your Hero Power to "negate" this, but in the end, you're paying 2 mana for a Spare Part to the hand. I think it's an interesting little card, though I am not sure what sort of deck would play this.

Solid 3-drop. This will glue together the Spiritwalker early game, as the Invoker and Tenderhoof from the classic set be able to generate large amounts of hand advantage.

A bit of an experimental card as this is only one of two cards to use Slumber as an offensive tool. it my be too invasive, so I will probably limit this application to GvG, where it cycles out relatively quickly. This card's big brother is an Epic, check it out below.

Thunderwalk returns as a GvG Rare. Very simple card, though I changed it to a Rare as hand buffing is still rather unique during the GvG period.

Mech, Spare Parts, and Immune synergy all rolled into a neat little package. I guess it's a cross between Cobalt Guardian and Stranglethorn Tiger. It's effect is far stronger, but it's a fair bit harder to activate that Cobalt Guardian's.

Pretty self explanatory, but a permanent Immune warrants this card's Epic rarity. This is definitely a combo card and after playing this, you'll want to focus on buffing the Immune Mech so it can continually swing at your opponent's face for game. (Wait until TGT's Lance Carrier :P)

The Spiritwalker's biggest removal card! A mix of Twisting Nether and Vanish, this card will be slightly less effective in the midrange matchup but very, very strong in the control matchup, as you could very well clog up your opponent's hand and burn a few. I'm on the fence if this should be 8 or 7 mana, but I chose 8 to play it safe.

Apparently, Jocas and Ashar were friends and rode on an airship or something.

Jocas is just a solid all-round 4-mana drop that can be played in any situation, something the Spiritwalker has thus far lacked. And, in almost all situations, he will give you an advantage. Of course, to counteract that, there's this thing: Emergency Coolant. That's the GvG-themed randomness there for you.

A very powerful Polymorph and the second of the hard removals. However, due to the Worgen Hero's playstyle, such a mana-heavy spell may be a bit too clunky. In addition, the Feral of the 2/2 won't activate as long as it never attacks or if it is the only minion. If your opponent is smart enough, you just paid for a really expensive Polymorph.

A great 1-drop, way more versatile than the old Worgen Rogue. Turns into a 3/1, taking down even some 3-mana minions and the ever-present Piloted Shredder.

TGT is all about a slower paced metagame, and fixing up classes. Worgen Hero actually lacked early game removal, and now they have a great one.

Perhaps with this card, a more late-game oriented deck is possible. Prevoiusly in playtests, Worgen Hero played very tempo-like, similar to tempo Warrior and Rogue. 

Lock and Load, boyz. Another card that patches up one of Worgen Hero's weaknesses: a lack of spells. Warrior spells fit very nicely into this deck. Stuff like Charge, or Slam, or Brawl? Great additions to the Worgen Hero's arsenal. Even Upgrade is welcome.

Before I get any flak, I KNOW WORGENS CANNOT BE PALADINS. BUT. If a human was previously a paladin, and then got transformed into a worgen... isn't that a worgen paladin? The card itself operates to the same degree like other great 2-drops that affect Hero Power, namely Steamwheedle Sniper and the new Fallen Hero.

A alternate single-target buff, perhaps replacing Curse of the Worgen. The card itself is pretty self explanatory. It's balanced well. 2/5 Taunt = 3.5 mana. Blessing of Kings, +4/+4 is also 3.5 mana.

A very, very interesting card. This weapon basically increases your Hero's damage to 3 each turn (Hero Power), but you gotta pay 2 mana each turn. It's a mix of... Dreadsteed and... Coldarra Drake... I guess? In any case, the Scythe certainly fits the TGT theme of Hero Power enhancement.

Does anyone get this reference? Crunch is a heavy 6-mana AOE, another thing Worgen greatly lacked. With this card, your opponents will now be more careful with their minion placement.

Gone with you, Archmage! This legendary was prevoiusly Archmage Arugal, who had a Battlecry that did a temporary Polymorph. That's boring. And un-TGT like. So, here's a Legendary that incorporates a fabled joust! This card turns joust on its head by giving you good outcomes BOTH ways. However, the catch is that they serve different purposes, these two outcomes, and it is 100% RNG based. Therefore, this is why both the Wolf (which is an actual WoW boss), and Red are quite powerful for their mana cost. For example. You wanted the Big Bad Wolf to save your butt from an aggro player? Well, you'd best hope you keep him. It's moments like these that balance out these two character's above-average stats. 

Clarification: The "Poison" mechanic, as I like to call it, states that "any minion DAMAGED by this card...". Therefore, when 'Lil Red deals 1 damage to them from her other effect, it would kill the target.
