A Hunter legendary minion WITHOUT beast synergy

and

Paladin card that equips a Weapon + does something else.

Similar to Rhonin (Vereesa's husband)

Like Tirion Fordring, can be brought back by N'Zoth, the Corruptor

Next: A Rogue card that interacts with class cards

So far the dragon number has worked because some activate off each other, but it has come up with some times where I don't have any. If that continues to be a problem, I think I'll replace Nightbane Templar for a dragon. 
As to the card draw, it tends to not be an issue if you get enough value out of cards, but on occasion it does lack. I'll keep testing and hopefully update the list.

Side note: I thought about Azure Drake which seems to address both problems but i think the spell damage is wasted and ends up making it weak. Will have to try it.

I Think that putting in Mukla, Tyrant of the Vale could work and you'd have to remove another high-cost card. I'd recommend taking out Dragon Consort in that case.

I definitely think that Deathwing, Dragonlord would work with the double synergy with N'Zoth and I'd reccommend taking out Ysera for him. You probably won't get much value from his deathrattle (If you take out Ysera), but the N'Zoth will be much better.

I think it should run the deck about the same if you change it.

So I was playing an Inspire Pally and I played my Frost Giant against this Priests two Djinni of Zephyrs and during his turn he Entombed my Frost Giant and the two Djinni of Zephyrs proceeded to Entomb themselves

The card Text on Djinni of Zephyrs reads : "After you cast a spell on another friendly minion, cast a copy of it on this one."

So my assumption is that because Entomb "makes" my Frost Giant his "friendly" minion by putting it in the priests deck, and therefore the Djinnis react accordingly.

So my question is : Should this interaction continue? (Albeit that Djinni is rarely played and this won't happen a whole lot)

I agree with Trinity809, Tirion is a very strong drop and has remained so because here are many ways to combat it. If you watched pro players in the past, holding onto a silence was commonplace when facing a paladin because they always had Tirion and the silence "killed" Tirion's value. Looking at the other paladin legendaries, Bolvar was sort of a flop because its too hard to get his value and Eadric is not significant against aggro.

And in the case of Mysterious Challenger, Blizzard had no clue that it would be so "strong" because paladins before mysterious challenger DIDN'T use any paladin secrets save for Avenge or the random Heroic Sacrifice.

Tl;Dr: Tirion is good and that's Ok. If you just plan for him with silence or polymorph/hex you can laugh at it.

Discover Paladin minion

Next: A Legendary Minion

Jouster that gains a deathrattle:

Next: A New Totem Minion

Flavour Text: "At the end of every portal is a new discovery. Its friendship, its always friendship"

Warlock Weapon with discard synergy

Next up: an all class, 7 cost legendary

An addition to Freeze mage. The secret can deal the damage to your own minions, so you could bait out a high cost minion by playing out only one low cost on an empty board. 

I'm sorta lazy, so i'll reuse my weekly card design's design.
4 mana 8/8

M'uru was sapped of his power by the Blood Elves to boost their own magic capabilities.

Next: 4 mana 4/3

Flavor Text: "If Velen says its ok..."

(Edited to fit restictions)

Here's a long one

Hearthstone:

 Weapons:

 Similar to Arcane Intellect but you get an extra card although two are not as good. Possible synergy with Mountain Giant Druid, Priest, Warlock, and Mage get a worse weapon because they are not weapon classes. Rogue is a "worse" weapon but instead gets a 1 cost hero power that combos. Warrior and Palladin get a worse weapon because they already have other ones to use instead.
The spell is supposed to represent the beginning of the game when you get your beginners gear.

Flavor Text: "Gear up and get questing"

Almost a cheaper Tree of Life but doesn't affect minions and takes a turn to activate.

Flavor Text: Fandral Staghelm says "If its broke, buy another one!"

Flavor Text: "Someone needs a timeout!"
