Aclazotz, Deepest Betrayal

Flying, lifelink
Whenever Aclazotz attacks, each opponent
discards a card. For each opponent who can't,
you draw a card.
Whenever an opponent discards a land card,
create a 1/1 black Bat creature token with flying.
When Aclazotz dies, return it to the battlefield
tapped and transformed under it owner's
control.
