Bison Whistle (V.1) - Magic: The Gathering | Avatar: The Last Airbender: Eternal (Rare) [TLE-131]

Bison Whistle is an artifact from the Avatar: The Last Airbender Eternal set that allows you to look at the top card of your library for just one mana and tap it. If it's a Bison card, you can put it directly onto the battlefield, while creature cards can be revealed and added to your hand, or you can send other cards to your graveyard. This card works well in decks focused on Bison creatures or strategies that benefit from graveyard interactions, though it relies on the top card of your library being the right type to be maximally effective.
