Treason of Isengard card art
Treason of Isengard steals a creature and an artifact in one shot — the kind of two-for-one tempo swing that can flip a board state before the target player gets to untap. The cost is real: you need Saruman, the White Hand or another amass-matters payoff in play to make the stolen creature a Ring-bearer, or the card reads as two mediocre effects stapled together.

Commanders with the highest synergy

01
Saruman, the White Hand

Saruman, the White Hand

57.3% of decks · synergy 0.53

Saruman, the White Hand runs Treason of Isengard in over half its decks because the spell directly feeds his amass trigger, letting you grow the Orc Army token while ripping away both a blocker and an artifact on the same turn.

02
Sauron, the Dark Lord

Sauron, the Dark Lord

35.0% of decks · synergy 0.30

Sauron, the Dark Lord wants every amass spell available, and Treason of Isengard pulls double duty by stripping an artifact — often a mana rock or equipment — while padding the Army that Sauron needs to close games.

03
Sauron, Lord of the Rings

Sauron, Lord of the Rings

34.1% of decks · synergy 0.29

Sauron, Lord of the Rings leans on a wide Orc board, and Treason of Isengard delivers an amass trigger plus a stolen threat that can be sacrificed or crashed in as a disposable attacker before the effect wears off.

In Commander, Treason of Isengard is firmly a Tolkien-themed amass deck card — it earns its slot in Saruman, the White Hand and Sauron builds but has no real home outside them. In Legacy, Vintage, and Modern, the effect is too slow and conditional for formats where four mana needs to close a game or break parity, not steal one permanent until your next turn. Pauper is the only non-Commander format where a tempo steal plus an artifact grab could theoretically matter, but the sorcery speed and Until-your-next-turn clause make it fragile against any instant-speed interaction. Outside of Middle-earth Commander decks, Treason of Isengard is a bulk rare with a narrow address.

Price Context

Current price

$0.22 bulk tier

At $0.22, Treason of Isengard is deep bulk — you're paying for the effect, not any scarcity premium. It's unlikely to appreciate unless amass becomes a competitive mechanic, so buy it for the deck and don't expect the price to move.
