Landfall-- whenever a land enters the battlefield
under your control, you may choose one that
hasn't been chosen this turn--
- Sacrifice a land, then you may put up to one
land from your hand onto the battlefield.
- Tellus gets +3/+0 and gains trample until
end of turn
- Target basic land you control becomes a 3/3 legendary elemental creature. It is still a basic
land.
