Maspera, queen of Shardana

Whenever a player plays a land card, that player may discard a card, then draw a card.
Whenever you would draw a card, you can play a land card from your hand or your graveyard instead.
If you do, until end of turn, target land becomes
a 2/2 green and blue Elemental creature with flying and 'Whenever this creature deals combat damage to a player, you may draw a card'. It's still a land.
