Thanks for the giveaways! Here's my new card design:
Vengeful Dead (max level version)
Death Splinter
4 mana
4 Melee attack
3 Speed
1 Health
No armor
Camouflage, Scavenge, Last Stand, Redemption
It's just a pile of corpses that grows bigger and bigger as the battle goes on until it finally rises up to avenge the fallen. It's only vulnerable (usually) in the first position, but it also can't attack until it gets there (again usually). But as a last resort you've got a big attacker (6 attack, hopefully around 15 health) to try to take down the enemy line, and if that fails you've still got a last ditch Redemption to try for a draw.
