The Necrobloom

Landfall — Whenever a land enters the
battlefield under your control, create a 0/1
green Plant creature token. If you control seven
or more lands with different names, create a 2/2
black Zombie creature token instead.

Land cards in your graveyard have dredge 2.
(You may return a land card from your graveyard
to your hand and mill two cards instead of drawing
a card.)
