Treasure Keeper
Artifact Creature — Construct
When this creature dies, reveal cards from the top of your library until you reveal a nonland card with mana value 3 or less. You may cast that card without paying its mana cost. Put all revealed cards not cast this way on the bottom of your library in a random order.

Treasure Keeper turns its own death into a free spell — any nonland card with mana value 3 or less cascades off the top when it dies, no mana required. The cost is randomness: you don't control what you hit, which makes Treasure Keeper a better fit in artifact-heavy shells than in decks that need precision, but in the right list it's a four-mana body that replaces itself on the way out and plays well with commanders like Gandalf the White who reward you for casting spells off the top.
Best Commanders
Commanders with the highest synergy
Gandalf the White
Gandalf the White triggers whenever you cast a spell from anywhere other than your hand, so Treasure Keeper's death-cascade fires his ability directly — each hit off the top is a free Gandalf trigger that can copy or redirect another spell you control.
Traxos, Scourge of Kroog
Traxos, Scourge of Kroog untaps whenever you cast a historic spell, and Treasure Keeper is an artifact that can cascade into additional artifacts on death — both the Keeper itself and whatever it flips off the top can chain untap triggers and keep Traxos swinging.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Treasure Keeper is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but Commander is the format where it actually earns a slot. In Commander, the singleton rule amplifies the cascade upside — hitting any of your best three-or-less-mana nonland cards feels meaningful, and sacrifice-matters or artifact-matters decks can engineer the death trigger reliably. In competitive 60-card formats like Modern and Legacy, the four-mana cost and randomness make it a non-starter against faster, more consistent options; cascade payoffs in those formats want guaranteed hits, not a coin flip. Oathbreaker is the one non-Commander format where a niche artifact-combo deck might consider it, but even there it's fringe.

Price Context
Current price
$0.13 bulk tier
At $0.13, Treasure Keeper is deep bulk — you're paying for the cardboard, not any scarcity. That price is stable and unlikely to move; it's widely available and sees no meaningful competitive demand to push it higher.
