Japheth, Explorer of Lands

Whenever Japheth attacks or blocks, you may pay {2}{u}{r}. If you do, choose one—
•Draw two cards, then discard a card.
•Create a 2/2 red and blue Elemental creature
token with haste and menace.
•Gain control of target land until end of turn.
Untap it. It becomes a 3/3 Elemental creature
with haste that’s still a land.
