Counterbore
Instant
Counter target spell. Search its controller's graveyard, hand, and library for all cards with the same name as that spell and exile them. Then that player shuffles.

In most cases, Counterbore will exile the targeted spell. Its first sentence counters the spell, which puts it into its owner’s graveyard. Its second sentence then removes it from the graveyard. However, there are some exceptions to this, as listed below.

The cards you’re searching for must be found if they’re in the graveyard, because that’s a zone everyone can see. Finding those cards in the hand and library is optional, though.

Counterbore has no effect on cards on the battlefield that have the same name as the targeted spell.
