Isareth, la Resucitadora

Text:

Toque mortal.
Siempre que Isareth, la Resucitadora ataque, puedes pagar . Cuando lo hagas, regresa la carta de criatura objetivo con coste de maná convertido de X de tu cementerio al campo de batalla con un contador de cadáveres sobre ella. Si esa criatura fuera a dejar el campo de batalla, exíliala en vez de ponerla en cualquier otro lado.

Rulings:

• 7/13/2018 Isareth’s triggered ability goes on the stack without a target. While that ability is resolving, you may pay <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" />. When you do, a second ability triggers and you pick a target creature card to return. This is different from abilities that say “If you do . . .” in that players may cast spells and activate abilities after mana is paid and the target creature card is chosen, but before that card is returned.
• 7/13/2018 Because all attacking creatures are chosen at once, a creature returned this way can’t attack during the same combat as it returns, even if it has haste.
• 7/13/2018 If a card in your graveyard has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, X is considered to be 0.
• 7/13/2018 If you somehow remove a corpse counter from a creature Isareth has returned to the battlefield, the replacement effect that will exile it continues to apply. The counter is only to help remind you which creatures will be exiled if they would leave the battlefield.
• 7/13/2018 If Isareth leaves the battlefield, the replacement effect continues to apply. If one of the creatures it returned would leave the battlefield, it’ll be exiled instead.
• 7/13/2018 Because to die means to be put into a graveyard from the battlefield, a creature that is exiled instead doesn’t “die.” Abilities that would trigger when it dies won’t trigger.
