Campeón de la cripta

Text:

Daña dos veces.
Cuando el Campeón de la cripta entre al campo de batalla, cada jugador pone en el campo de batalla una carta de criatura con coste de maná convertido de 3 o menos de su cementerio.
Cuando el Campeón de la cripta entre al campo de batalla, sacrifícalo a menos que se haya usado para lanzarlo.

Rulings:

• 5/1/2006 The first triggered ability isn’t targeted, so the creature cards aren’t chosen until the ability resolves. Each player chooses which creature card from their own graveyard to return. If a player doesn’t have an applicable creature card, that player does nothing. If a player does have any applicable cards, that player must return one to the battlefield.
• 5/1/2006 If this enters the battlefield in a way other than announcing it as a spell, then the appropriate mana can’t have been paid, and you’ll have to sacrifice it.
