Defender, reach, trample Landfall — Whenever a land enters the battlefield under your control, put a +1/+1 counter and an anger counter on Kra-Kos. Then if it has three or more anger counters, Kra-Kos loses defender. Remove an anger counter from Kra-Kos: Target creature gets +1/+1 and gains haste until end of turn. {T}: Add {B}{R}{G}. Spend this mana only to cast Elemental spells or activate abilities of Elementals.
