Next: A legendary Draenei minion for a Non-Divine (Priest, Paladin, Shaman, Druid.) class.

Next: Continue this theme.

Token/Bolster warrior! wooooo

Kezan Mystic yoink

Forces your opponent to clear the board asap or deal with a bunch of little explosions preventing small minions. You need a minion or two on the board to get the effect to trigger, it does copy the effect before dealing damage so that it will spread if it kills an enemy minion.

Next: A Chaos Bolt spell for warlock, but make it unsual not just "deal x amount of damage".

"Mages make the best portals! just ask medivh!"

After it's played at the end of each turn a dark portal would burst out of the ground and a minion would spawn in with a redish light animation. I love the random minion summoning effects mages have and this card gives both players the chance to enjoy the fun! RNGesus save your soul.

"To bad it can't reload itself!"

It'd have an animation where it shoots gears and stuff (spare parts!)

Next: Another gimmicky card.

Obvious spare part synergy, the idea was whenever you played a spart 

Next: A Legendary Draenei for a class other than Paladin or Priest. (broken don't count!)

"He's pretty lazy when his rider's away."

Next: A Ghost, use wow art from somewhere!

Yolo!

Next: Another really strong effect but something to balance it out.
