mtg 100 card deck Ultra Pro - 100+ Box for Magic: The Gathering Commander Masters - Anikthea, Hand of Erebos Artwork play 100 Magic: The Gathering | Lorwyn

This card, Fabricate, would be beneficial in a deck that heavily relies on artifacts for its strategy, such as an artifact-focused deck in Commander or Modern formats

Welder also yields loads of value from quite a wide selection of your cards

Its good to pair with red discard and draw effects, stocking dragons for later use, or to synergize with red-black dragons like Bladewing the Risen

You can call it canon at any time because thats what the multiverse implies, but at the same time those promotional cards were just card styles and not actual standalone cards like the Street Fighter or Walking Dead Secret Lairs
