Creeper - A simple one drop similar to Mana wyrm or Tunnel Trogg, it felt like the perfect combination with the Cache mechanic. It is very intuitive to others who have used cards like Mana Wyrm as to how it works, and can also make for early game choices when you have two of these on the field. 

Memory( ) - This card is a bit different in terms of the Turn mechanic. It allows for a discounted Arcane Intellect, but requires the player to have attacked with a minion, otherwise it is a worse Shiv. I think it shows how Turn isn't strictly beneficial to the player, and won't always be easy to make happen.

Mother - We have seen a lot of 4 mana 3/5's and thus it felt good to do another one with a simple effect. It felt good for a common, and while not strong like say Piloted Shredder, can go toe to toe with it, and provides an equally good alternative effect.

Claw - This card I find most akin to Savage Combatant. It is one of the few Process minions with a higher attack than health, and has the potential for a ton of damage output. Of course, that damage may not be worth it compared to some of the other Cache effects. 

Mute( ) - This was originally a basic card, until I remembered Silence was not allowed to be used. Therefor, it got moved to this set, where it acts like Shiv except with silence. Compared to owl, it is the difference between an 2/1 or drawing a card.

Crash( ) - This card is a good simple Turn card. It is the 1 mana deal 2 damage spell that most classes have, with an upside if you have yet to attack with a minion. A minor thing, as more often than not it will be 3 damage, but there are times like when dealing with cards like Dr. Boom, you want to see where the random effects land before casting spells.

Ping( ) - The Singer doesn't have a wide amount of AoE, especially not early in the game. This was made to help with that problem, but not solve it. The class should have weaknesses, and this is one of them. Similar to mage, they should thrive off of having board control, and using powerful single target spells to achieve that goal. 

In Circles - This card is the second 'Song' card for the singer. It too provides a more weird and unique effect, as every other ability is more meant for dealing damage or controlling the board. Plus it is a really good song... like go look it up and listen.

Jerk - This card shows the duality Turn can bring, either making an Infernal type effect, or a Fire Elemental effect. A 5/6 is nothing to sneeze at either, this card is meant to be competitive with Loatheb, providing two potentially useful effects for the same cost as him.

Mask( ) - Another utility card. I love this one honestly because it works so well with Turn. If no minions have attacked, let one through taunt, otherwise run through yourself. It requires opponents to deal with your big minions, or can allow the hero a way to bypass taunts to use one of their weapon enhancing effects on a creature. 

Junction Jans: Even Red has gotta eat sometimes. This spell works like a cross between Flash Heal and Holy Light. It's limited to the hero partially due to theme (her minions are all robots), and to cheapen the cost to allow for a miracle Singer deck.

Help( ): This card is a cheap way to get 2 damage on the board, along with 2 bodies. This too allows for a miracle Singer, but does the more important job of cheaply activating other spells Turn( ) mechanic (see above). It is best compared to Living Roots and Mirror Image.

Void( ): This card fits the theme of Red doing a lot of the dirty work with her weapon. It'll often only be used once, as Red will have no other weapons aside from the Transistor. It allows for a buff to a weapon aside from damage or durability, and essentially acts as an assassinate that cannot bypass taunt.

Bounce( ): This card is Reds board clear, should it work. It requires hitting the right targets in the right order to work, and can swing the early game. If cast on an empty board, it is a 3 mana fireball. 

Switch( ): This card acts like Shadow Madness without the attack limit. A good card if used efficiently, it can have a major impact on games, but requires ample set up and mana. 

Mesmerize( ): Frost Nova with card draw, this card represents Red enchanting her opponents with her voice. It is one of her few ways of stall, but more expensive than what other classes may have access to. 

Builder: A simple 2/3 that gives an upside. Good draw and planning could lead to multiple uses from weapon buffs, or a decent early game body.

Clucker: This card is similar to Flame Juggler, but will ideally see more play due to it's higher damage, and more limited RNG. The loss in stats shouldn't have too big of an impact, but can still make a difference versus certain classes. 

Snapshot: This card has the potential to be just as irritating for aggro decks as this minion was in the actual Transistor game. Thematically it flashes snapshots of the enemy at them to distract them, hence simply giving it Taunt. 

Young Lady: The Savannah Highmane, or Imp Gang Boss of the Singer, it has the stats of Reno Jackson with a great upside. It should hopefully provide a strong contender for this classes 6 drop slot, and doesn't use any secrets :D.

I really like all your cards! My only question: How do Kill() and Switch() work together?"

Kill() and Switch() would depend on the order played, you either kill the minion right out, or switch the minion to your side and it immediately dies.

Help( ) - A cheap costing spell similar to living roots or mirror entity. My primary reason for including this card is that it activates the classes Turn() mechanic so easily, (this will be seen in future sets). I'm avoiding cards like savage roar or power of the wild to keep from making a Fon+SR combo. It is also cheap to hopefully go with the miracle feel that I think this class is going.

Bounce( ) - Essentially a random AoE removal, or a 3 mana fireball. The discount is for the random effect, and split damage making it not too surefire for straight removal. I feel it is good early game, and significantly weaker late game. My biggest fear is it being a bit over the top and OP in the early game.

Jerk - Essentially a slightly worse, or different, Baron Geddon. This is meant to help the classes late game, for the potential of a control deck. Your essentially getting a consecrate and a minion, however unlike Baron Geddon, it only goes off once and not every turn.

Young Lady - The shade is just a vanilla minion, so I find it like this classes Savannah Highmane. I'm torn between it being 5 or 6 mana, as if it dies in one hit, it might as well be a 5/7 minion, where as if it takes many hits, it can get ridiculous.

 Kill() - This is pretty much a 4 mana assassinate that cannot bypass taunts. It too fits with the miracle theme I think, and provides a way to buff the weapon outside of straight damage. The Transistor will be the only weapon available to the class (outside of Blingtron), so through limiting buffs, it is not likely this will see more than one use per cast (2 with the ??? minion)

Mute() - Most classes I noticed has a sort of basic X + draw a card attached. I think it is comparable to the new flare, or shiv, a 0 mana effect (from priest) and a card draw. I think making it one mana would be too good, like how the old flare was. I thought about attaching this to the weapon similar to switch() and kill() but didn't want to overuse a mechanic

Switch() - This is similar to shadow madness, again cheap but requires the hero power to activate. It doesn't have the a maximum attack, which I think opens it uses, at the disadvantage of being unable to bypass taunts.

??? - A standard 2 mana minion, buffs durability. I don't have a good name for it yet, but I think that it fits the class, proper set up would allow for multiple uses of the above buffs. More of a utility card with a cost, like sorcerers apprentice for mages

Snapshot - A simple, non complex minion. I was afraid of having too many things with unique effects, and most classes have at least a minion similar to this so I felt like this would be a fair idea. I also don't know if it would really fit the theme.

Junction Jans - A mix of flash heal and holy light, it removes the targeting capability, but reduces the cost. Another miracle style card, adding to the classes overall survival.
