Ashaya, the Life Gorger

Trample, Annihilater 4
When Ashaya, the Corrupted enters the battlefield, all lands become basic colorless lands with "{t}: add {c} to your mana pool." Put a +1/+1 counter onto Ashaya for each land turned this way.
{3}{g}{b}: Target creature's power and toughness become 0/1 and it loses all abilities. You gain life equal to the creature's original toughness.
