Tora Lyn, Terrain Emissary

Landfall - Whenever a land enters the battlefield under your control, put a +1/+1 counter on each land you control equal to the number of basic land types you control. They become 0/0 Elemental creatures with haste. They are still lands.
Remove all +1/+1 counters from lands you control at your end step. You gain life equal to
the number of +1/+1 counters removed this way.
