Dennis Rodman, the Worm

Offensive Rebound (Whenever one or more creatures
you control become blocked, put a -0/-2 counter this creature. There's an additional combat phase after
this phase. At the beginning of that combat, untap all creatures you control. This ability triggers only once
each turn.)
When Dennis Rodman, the Worm enters the battlefield, search your library for a basic land card,
put it on the battlefield tapped and shuffle your
library.
