Arctiguana

Islandwalk
Nonbasic lands are Islands.
Islands have "{t}: Add two mana of any one
color."
Whenever Arctiguana deals combat damage to a
player, you may search your library for an Island
or nonbasic land card, put it onto the battlefield
tapped, then shuffle your library.
{1}{u}{b}: Transform Arctiguana if you have
one or more poison counters.
