Agraxlore Firebred

Double strike
Agraxlore Firebred enters the battlefield with a
color counter on it (When a color counter is put on
a non-land card, you may choose to have that card be
any color as long as that color mana is in that card's converted mana cost.)
Whenever you play a land, another target
creature you control with double strike gets
+2/+0 until end of turn.
