Orvask, Tunneling Terror

Whenever a land you control is put into a
graveyard from the battlefield, add a +1/+1
counter to Orvask, Tunneling Terror. When
Orvask, Tunneling Terror is put into a
graveyard from the battlefield, create a treasure
token for each +1/+1 counter on it. You may
cast Orvasrk, Tunneling Terror from the
graveyard for {5}{b}{g}. If you do, it gains
haste and basic landwalking until end of turn.
