Gleaming Splendor

A narrow answer to Opt, Sleight of Hand, and Stock Up decks; it can turn their selection into mana but is blank against creature-heavy opponents.

Could be wrong if If draw-heavy Izzet shells remain dominant and Treasure materially improves control's tempo, it could become a recurring sideboard card.

It can punish cantrips and draw engines, but a two-mana permanent that neither disrupts nor affects the board is a steep Pioneer cost.

Could be wrong if Frequent extra-card draw from leading blue decks could make the delayed Treasure return more reliable than expected.

Modern demands immediate interaction or a stronger payoff; giving a Treasure for an opponent's extra draw is too delayed to stop its game plan.

Could be wrong if A white shell that converts cheap Treasures into a resilient engine could create a narrow home.

Brainstorm and Ponder can trigger it, but one delayed Treasure from a two-mana enchantment is far below Legacy's efficient hate and mana engines.

Could be wrong if If a prison shell can exploit repeated Treasure triggers without losing tempo, cantrip density may support testing.

Much weaker than Rhystic Study, but multiple opponents and wheels can yield several Treasures; its symmetric draw activation fits only dedicated shells.

Could be wrong if Optimized tables may not provide enough voluntary extra draws, leaving it as an underpowered group-hug card.

It does not affect the battlefield, opponents seldom draw extra cards, and its costly symmetric draw ability usually helps them as much as you.

Could be wrong if Unrevealed draw-forcing, Treasure, or sacrifice synergies could make occasional triggers worth the weak baseline.
