March of the Machine: Aftermath (MAT) 

Legendary Creature - Human Druid 

3/3 

At the beginning of combat on your turn, up to one target land you control becomes an X/X green and blue Bird creature with flying and haste until end of turn, where X is the number of cards in your hand. It's still a land. // Whenever a land creature you control deals combat damage to a player, draw a card.
