I can think of a better version...
Balance/Equilibrium
cost: 7

Ability: Target creature's stats are leveled.
Note: Creature's Attack and Defence become the result of this equation
((Creature Attack + Creature Defence)/2)RoundDown
So effectively it just averages the two of them. Instantly.
So, an Armaggio is a 1/25? He becomes a 13/13
Colossal Dragon is 8/30? He becomes 19/19
Ruby Dragon is 15/2? He becomes 8/8
Obsidian Dragon is 12/6? He becomes 9/9
The only problem is:
Flying Titan is 7/70? He would become 38/38... So maybe Titan needs a nerf, or this can only effect Creatures. Not Flying Weapons.
