5 rulings from Wizards of the Coast
- 20 September 2014Dead Drop doesn't target any creature. The target player could sacrifice a creature with hexproof, for example.
- 20 September 2014The target player chooses which creatures they will sacrifice as Dead Drop resolves. If the player controls only one creature at that time, they will sacrifice it.
- 19 March 2021Delve doesn't change a spell's mana cost or mana value. For example, Treasure Cruise's mana value is 8 even if you exiled three cards to cast it.
- 19 March 2021You can exile cards to pay only for generic mana, and you can't exile more cards than the generic mana requirement of a spell with delve. For example, you can't exile more than seven cards from your graveyard to cast Treasure Cruise unless an effect has increased its cost.
- 19 March 2021Because delve isn't an alternative cost, it can be used in conjunction with alternative costs, such as flashback. It can also be used to pay for additional costs that include generic mana.
