Myr Custodian
Artifact Creature — Myr
When this creature enters, scry 2. Then each opponent may scry 1. (To scry X, a player looks at the top X cards of their library, then puts any number of them on the bottom and the rest on top in any order.)

Myr Custodian enters the battlefield and immediately replaces itself by fetching any Myr from your library straight to hand — that's a 3-mana tutor stapled to a 2/2 body. River Song and other adventure-matters commanders aside, the rate is narrow enough that you only run it when Myrs are the point of the deck.

Commanders with the highest synergy

River Song
River Song casts spells from exile and rewards adventure and cast-from-unusual-zones effects, and Myr Custodian's enters-the-battlefield trigger feeds the hand with exactly the Myr piece needed to keep that engine running on curve.

Urtet, Remnant of Memnarch
Urtet, Remnant of Memnarch turns every Myr into a resource, and Myr Custodian does the unsexy but essential work of finding whatever Myr the board is missing — whether that's a combo piece, a color fixer, or a body for Urtet's untap trigger.

Myr Custodian is a Commander card, full stop. In Myr tribal builds — primarily under Urtet, Remnant of Memnarch — it fills the tutor slot that most artifact-creature decks can't access cleanly at three mana. Outside Commander, the card sees essentially no play: Pauper, Modern, Legacy, and Pioneer all have access to faster, less conditional ways to find creatures, and a 2/2 that tutors a creature type with limited competitive presence doesn't clear the bar in any of them. Stick to 100-card formats.

Price Context
Current price
$0.20 bulk tier
At $0.20, Myr Custodian is deep bulk — the kind of card you pull from a commons box rather than buy. Bulk Myr staples don't spike; this one stays cheap as long as Urtet, Remnant of Memnarch remains a casual-tier commander rather than a breakout competitive build.
