Glass of the Guildpact drops a +1/+1 counter on every multicolored creature you control at end of turn — for two mana, that's a compounding board buff that gets out of hand fast in the right shell. General Ferrous Rokiric is the obvious home, where every multicolored spell floods the board with Golems that immediately start stacking counters.

General Ferrous Rokiric
General Ferrous Rokiric generates a stream of multicolored Golem tokens, and Glass of the Guildpact turns that token engine into a permanent size advantage — every end step, every Golem grows, often faster than opponents can answer them.

Glass of the Guildpact is almost exclusively a Commander card — the effect is slow and cumulative, which means it needs a multiplayer game with enough turns to compound. In Legacy, Modern, and Pioneer, a two-mana artifact that does nothing until end of turn and requires a multicolored board simply doesn't make the cut against faster threats and efficient removal. Commander is where it belongs: multicolored synergy decks run plenty of creatures to clock, and a bulk rare that grows your whole board every single turn is exactly the kind of quiet engine that wins long games.

Price Context
Current price
$0.25 bulk tier
At $0.25, Glass of the Guildpact is firmly bulk — near-zero financial commitment for any multicolored Commander deck that can use it. Bulk rares with narrow but genuine synergy tend to stay cheap indefinitely, so there's no urgency to buy in quantity, but grabbing a copy now costs less than a pack of sleeves.
