Tanglefoot Treant

Trample
Whenever a land enters the battlefield under
your control, you may put a +1/+1 counter on
target creature you control. Whenever
Tanglefoot Treant deals combat damage to a
player, you may search your library for a land
card, reveal it, put it into your hand, then shuffle
your library.
Rooted in the earth, it grows ever stronger with each passing day.
