Aggressive Geomancer

Mountains you control have First Strike.
Swamps you control have Deathtouch. Forests
you control have Trample.
Whenever a land card is put into your graveyard,
add one mana of any color that land could
produce.
{b}{r}{g}: Target land you control becomes a 5/4 Elemental creature until end of turn. It's still a
land.
