Campeón de la cripta

Text:

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

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.
