Paladin of the Ancients

Defiance (untap any number of creatures you control that share a color with this creature and reduce
damage dealt to this creature equal to the number of creatures untapped this way.)
At the beginning of your end step, if Paladin of the Ancients blocked a creature, search your library for a basic land and put that into the battlefield tapped, then shuffle.

"I'll try to keep the peace in these lands."
