Pithing Needle

Pithing Needle affects cards regardless of what zone they're in. This includes cards in hand, cards in the graveyard, and exiled cards. For example, a player can't cycle Eternal Dragon or return an Eternal Dragon from their graveyard to hand if Pithing Needle naming Eternal Dragon is on the battlefield.

You can name any card, even if that card doesn't normally have an activated ability. You can't name a token unless that token has the same name as a card.

If you name a card that has both a mana ability and another activated ability, the mana ability can be activated but the other ability can't be activated.
