Johann, Apprentice Sorcerer

The Izzet spellslinger has a long history of top-of-library payoffs, from Melek, Izzet Paragon to Future Sight, but most of them read a specific spell off the top and cast it for free. This one takes the opposite tack: it shows you the top card at all times, then lets you cast one instant or sorcery from there each turn at full cost, subject to normal timing. That combination is the whole point. Cards that hide information reward gambling; being able to see your top card at any time turns the ability into something closer to a second hand you can plan around, because you always know whether next turn holds a burn spell or a land. The once-per-turn clamp and the "you still pay its costs" clause are what keep it from spiraling: this is card advantage, not a mana engine, and the 2/5 body signals the design intent, a defensive shell that survives a turn cycle so the incremental card economy can compound rather than a threat racing the clock. Where earlier reveal-effects wanted you to jam whatever surfaced, this one asks you to sequence draws and holds against a known top card, rewarding a build with a high density of cheap interaction and cantrips so the reveal is rarely dead.
