The Queen, Mother of the Hive

Vigilance, menace

Other Xenomorphs you control get +1/+1.

Whenever a creature an opponent controls would die, instead exile it with three gestation counters.
At the beginning of your upkeep, remove a gestation counter from each card in exile.
When the last gestation counter is removed from a creature card, create a token that's a copy of it, except its a black xenomorph in addition to its other colors and types.
