Sanar, Unfinished Genius // Wild Idea

In Commander, Sanar, Unfinished Genius // Wild Idea slots cleanly into any Izzet spellslinger shell that can protect a creature for two or three turns — the payoff is strong enough to justify that ask. Competitive Commander tables will kill it on sight before the flip, so it plays better at mid-power where removal is less dense. In Standard, Pioneer, and Modern it's a legitimate build-around threat: three mana for a repeatable free spell is ahead-of-rate if you can flip it, and those formats have the redundancy to build toward the counter threshold reliably. Legacy and Vintage don't need it — those formats already have faster free-spell engines — but it's not embarrassing there if a specific shell wants it. Oathbreaker treats it much like Commander, where the smaller life totals help you close before opponents can answer it repeatedly.
