Even more Delve! Yesterday we learned that you can use Delve as a payment for an alternate cost such as Flashback, because Delve is a payment, not an alternate cost itself. So how does Delve interact with additional costs? Well, that depends! If there were a Delve spell with Kicker, you could use Delve to pay the colorless portion of the kicker just fine. If your opponent has out a Thalia, you can Delve away an additional card to cover her ‘tax’ effect (in fact, you can use tax effects to your advantage with Soulflayer– more colorless mana to pay for means more potential Delve bodies to boost him up!). However, things such as Mana Leak are not a cost paid when casting the spell- by the time your opponent is throwing a Mana Leak at you, your spell is bought and paid for. Delve has done what Delve does. No matter how badly you want to, you can’t just pitch 3 cards from your graveyard to exile to pay for your opponent’s Mana Leak, because that’s not paying for the cost of the spell!
