Deceiver of Form
Creature — Eldrazi
(
represents colorless mana.)
At the beginning of combat on your turn, reveal the top card of your library. If a creature card is revealed this way, you may have creatures you control other than this creature become copies of that card until end of turn. You may put that card on the bottom of your library.

Deceiver of Form turns a single large attacker into a army of copies — if the top card of your library is a creature, every creature you control becomes that creature until end of turn, which means one Biovisionary trigger becomes four, one Eldrazi becomes twelve. The cost is real: seven mana and a coin-flip dependency on your library's top card keep it out of efficient shells, but in any deck that stacks its library or cheats on mana, it closes games in ways most finishers can't.

Commanders with the highest synergy
Zhulodok, Void Gorger
Zhulodok, Void Gorger makes Deceiver of Form cast for free off its cascade trigger, and since Zhulodok puts other Eldrazi into play, you routinely flip into another enormous creature on the reveal — the combination turns a board of colorless threats into a lethal, uniform wave on the same turn you resolve it.

Commander is where Deceiver of Form actually lives — a seven-mana do-nothing-until-combat card needs a multiplayer board state to justify itself, and the combination of 40 life totals, token generators, and library manipulation creates exactly the right conditions. In Legacy, Modern, and Pioneer it's legal but functionally unplayable; the formats move too fast for a seven-drop that requires setup and can whiff entirely if the wrong card is on top. Vintage has the raw power ceiling to support it theoretically, but the format's best strategies don't need a combat-step transformation when they can win on turn one. Stick to Commander, specifically in colorless Eldrazi shells or any list willing to run top-of-library control alongside it.

Price data isn't available for Deceiver of Form at the moment, so check Scryfall or TCGPlayer for current market values. Given its narrow competitive application and dedicated Commander fanbase, it tends to sit in the budget-to-mid range — worth picking up if you're building Zhulodok or any mass-copy strategy, not worth speculating on.
