Morstyl Constrictor

Morstyl Constrictor's power and toughness are
each equal to the number of lands you control
with different names.
When Morstyl Constrictor dies, choose one—
• Put a X cards from the bottom of your library
into your graveyard, where X is its power.
• Trawl X, where X is its power. (Put up to X
other cards in your graveyard on the bottom of your
library in any order.)
