Arcane Infusion - Innistrad: Double Feature (Uncommon) [DBL-210]

Arcane Infusion allows you to dig through your library for an instant or sorcery card, providing card advantage while also letting you control what goes back on the bottom. Its flashback ability means you can use it again from the graveyard, making it a valuable resource in Izzet UR decks that focus on spellcasting and recursion. However, its reliance on finding specific card types may limit its versatility in non-spell-heavy strategies.
