Itazura, Lingering Wick

Four mana, no immediate effect, and an upkeep trigger that can hand over a free spell are far too slow and risky for Modern.

Could be wrong if Unusually reliable library stacking with uncastable or harmful reveals would be required.

Legacy's cheap interaction and powerful spells make a delayed four-mana creature that grants an opponent free casting untenable.

Could be wrong if A novel setup shell that makes every opposing cast ineffective could alter this, but none is supplied.

Multiplayer lets its controller choose among tied zero bids, but repeatedly donating free spells is still worse than a slow, one-card upkeep return.

Could be wrong if Political play and reliable topdeck control may make it a niche value engine in a specialized Izzet shell.

Its 1/5 body can block, but on most upkeeps an opponent receives a free creature or spell while you only recover one leftover card.

Could be wrong if A slow environment with many uncastable reactive spells could make its repeated selection less punishing.
