Ruby Collector

{W} · Creature — Human Detective
Uncommon · Mystery Booster Commander Edition · Art by Cristi Balanescu

When you attack with three or more creatures, conjure a card named Mox Ruby into your hand. This ability triggers only once. {1}{R}: Creatures you control get +1/+0 until end of turn.

Predicted power

Standard — Eng.NLUsr.—

Pioneer — Eng.NLUsr.—

Modern 48 Eng.C-Usr.—

Boros Aggro may test it, but it is far less immediate than Guide of Souls (88); the Mox requires a developed board and survival.

Best home Boros AggroBand fringeConfidence 61%

Could be wrong if Modern Boros shells may be too streamlined and interaction-heavy for a three-attacker payoff to matter.

Legacy 40 Eng.D+Usr.—

Boros Aggro can exploit a delayed Mox, but Collector is less immediate than Voice of Victory (54) and fragile before its payoff.

Best home Boros AggroBand fringeConfidence 57%

Could be wrong if Legacy's speed and cheap removal may make assembling three attackers with Collector in play unrealistic.

Pauper — Eng.NLUsr.—

Commander 61 Eng.B-Usr.—

Cheaper than Commander's Sphere (55) but conditional; token decks value the one-shot Mox plus a repeatable mana-sink anthem.

Could be wrong if Matching decks may prefer immediate ramp, stronger anthem effects, or more reliable token payoffs.

Limited 60 Eng.B-Usr.—

A protected 1-drop can turn a wide attack into a free Mox and later pump the team; its weak floor and red need prevent premium status.

Could be wrong if Unknown token density, format speed, fixing, and removal determine how consistently it can trigger.

“Ruby Collector converts a successful wide attack into delayed red acceleration and can turn that mana into team damage.”

AI prediction made before release — not a measured result. Real performance data replaces this once the set is legal and tournament results come in.
