Accursed Awakening

At the beginning of your precombat main phase, if you control fewer creatures than each opponent, return target creature card from your graveyard to the battlefield. That creature gains haste and persist. Then, if you control 4 or more creatures, Accursed Awakening deals 2 damage to each creature you control.
The Undead Legion fight eternally against anything corrupted by the Abyss, even themselves.
