battle - cschladetsch/Unity3dCardChess GitHub Wiki
One Creature Battles another simultaneously by comparing their Attack and Health values.
Each such creature deals damage according to its Attack value. If that value (including any Buffs) is greater than the creature it is attacking, the opposing creature dies.
The converse is also true. So if a creature with 1/1 attacks another with 1/1, they both die simultaneously.
