Evaxath, Mistfall Maniac

Precision (Whenever this creature is blocked by a creature with power 1 or less, it gains trample until
end of turn.)
Other Darkspawn creatures you control have islandwalk (They can't be blocked as long as defending player controls an Island.)

At the beginning of your upkeep, you may sacrifice a creature and add {u}{u}{u} to your mana pool.
