Landfall: Whenever a Land enters the battlefield under your control, you may pay X {p/g}{p/u}, where X is the amount of Bird creature tokens you control + {1}. If you do, create a 2/2 green blue Bird creature token with flying.

Whenever one or more Birds you control deals combat damage to a Player, you may return an untapped Land you control to your hand. Do this only once each turn.
