Aerlinds Crest

{flavor}Whenever a Goose you control enters the battlefield or dies, you gain 1 life. Then, if you have gained 10 or more life this turn, you may choose an opponent. That opponent gets a Commander counter from Aerlind. You may assign no more than 2 Commander counters this way each turn. If a player has 21 or more Commander counters from Aerlind, they lose the game.{flavor}
