black attack

Destroy all creatures. They can't be regenerated.

Flying Wither (This deals damage to creatures in the form of -1/-1 counters.) Creatures your opponents control with counters on them can't attack or block.

Each player returns each creature card from their graveyard to the battlefield with an additional -1/-1 counter on it.

, Remove a -1/-1 counter from a creature you control: This creature gets +3/+3 until end of turn.

When this creature enters, up to X target creatures each gain intimidate and haste until end of turn, where X is your devotion to black. (A creature with intimidate can't be blocked except by artifact creatures and/or creatures that share a color with it. Each in the mana costs of permanents you control counts toward your devotion to black.)
