Some equivalents to Foundry of the Consuls (colorless lands that create artifact creature tokens) are:
- Spawning Pit (creates 2/2 colorless Spawn artifact creatures, via sacrificing creatures)
- Mishra's Factory (becomes a 2/2 artifact creature, but doesn't make tokens)
- Urza's Factory (creates 2/2 colorless Assembly-Worker artifact creature tokens)
- Mirrex (creates 1/1 colorless Phyrexian Mite artifact creature tokens; produces colorless mana)
Reason: These are all colorless lands or artifacts that can generate artifact creature tokens. Urza's Factory is the most direct comparison.
