Urza, Prince of Kroog + Metalworker + Lightning Greaves
How it works
- Activate Lightning Greaves' equip ability by paying 0, attaching it to Metalworker.
- Activate Metalworker by tapping it and revealing at least three artifact cards from your hand, adding at least six C.
- Activate Lightning Greaves' equip ability by paying 0, attaching it to Urza.
- Activate Urza by paying 6, creating a token copy of Metalworker that is a 1/1 Soldier.
- Activate Lightning Greaves' equip ability by paying 0, attaching it to the Metalworker token.
- Activate the Metalworker token by tapping it and revealing at least three artifact cards from your hand, adding at least six C.
- Repeat from step 4.
- If you have four or more artifact cards in hand, this combo nets infinite colorless mana, and you may target any artifact you control to get infinite copies of them.
This clever loop uses Urza, Prince of Kroog to rapidly multiply your resources, leveraging his activated ability to churn out 1/1 token copies of Metalworker. Because Metalworker's mana-generating tap ability doesn't require a tap symbol that specifies the creature's original name, the newly created token can immediately tap to reveal artifact cards from your hand for a massive influx of colorless mana. Lightning Greaves is the oil that keeps this engine turning, swapping its equipment back and forth for zero mana to grant haste and ensure that both the original Metalworker and its fresh token copies can tap the moment they enter the battlefield. Meanwhile, Urza, Prince of Kroog provides a passive static buff that pumps your entire mechanized army with +2/+2, ensuring your growing horde of artifact creatures is as lethal as it is infinitely wealthy.
