Sibsigs arrastrafangos

Excavar. (Cada carta que exilies de tu cementerio al lanzar este hechizo cuenta como un pago de .)
Cuando los Sibsigs arrastrafangos entren al campo de batalla, regresa la carta de criatura objetivo de tu cementerio a tu mano.

Rulings:

• 11/24/2014 You exile cards from your graveyard at the same time you pay the spell’s cost. Exiling a card this way is simply another way to pay that cost.
• 11/24/2014 Delve doesn’t change a spell’s mana cost or converted mana cost. For example, the converted mana cost of Tasigur’s Cruelty (with mana cost <img src="/Handlers/Image.ashx?size=small&amp;name=5&amp;type=symbol" alt="5" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=B&amp;type=symbol" alt="Black" align="absbottom" />) is 6 even if you exile three cards to cast it.
• 11/24/2014 You can’t exile cards to pay for the colored mana requirements of a spell with delve.
• 11/24/2014 You can’t exile more cards than the generic mana requirement of a spell with delve. For example, you can’t exile more than five cards from your graveyard to cast Tasigur’s Cruelty.
• 11/24/2014 Because delve isn’t an alternative cost, it can be used in conjunction with alternative costs.
