Babaiki Pilgrim

This creature gets +1/+1 for each Forest you
control, +1/+0 for each Swamp you control, and
+0/+1 for each Plains you control.
Whenever this creature deals damage to a player
who controls more lands than you do, you may
put a land from your hand onto the battlefield. If
you don't, that player sacrifices a land.
Every year these creatures can be seen traversing great distances to gather at a secret location.
