Just two I’ve noticed so far,

Crystalline Entity, 8 mana, 7/7 Flying when it enters (if it was cast) destroy all non artifact creatures

The Holodeck, 7 mana, once a turn you may play any permanent card from outside the game or from your graveyard

* they’re both artifacts. So less cards in the deck clogging up your metalworker hand that are not artifacts

* crystalline entity blows up non artifact creatures, so I guess no eldrazi in the deck

* I realize this is an old combo but bears repeating, metalworker goes infinite with 6 mana and staff of domination in play. For infinite mana and infinite life oh and infinite card draw

- Tron already makes a lot of mana. When metalworker was being played we didn’t have planar nexus

Conspiracy Theory : crystalline entity has a clause specifically to address not tutoring this directly into play with kuldotha forgemaster. Maybe wizards is already considering this spell in a metalworker deck. Forgemaster would still be able to surprise win out of nowhere with blightsteel colossus which was really awesome. Oh and also no goblin weldering I guess was the main consideration

Has anybody been thinking of dusting off Metalworkers?

Ps - I realize this is a brand new account I just deleted a Reddit account and made a new one
