The Everforger

Even artifact decks are unlikely to spend six mana on an engine with no cast trigger and no protection in Modern's fast, efficient environment.

Could be wrong if Fast mana or a new artifact-combo payoff could make one copied creature per turn materially stronger.

Ancient Tomb can help cast it, but a six-mana, removal-vulnerable engine that needs a later spell is far below Legacy's usual efficiency bar.

Could be wrong if A Tomb-based artifact shell with unusually powerful cast or token-copy payoffs could create a fringe use.

As commander, it expands artifact and Equipment color access and doubles one qualifying permanent spell each turn, a meaningful engine despite six mana.

Could be wrong if Basic-land-only color access outside the exception and the need to untap may make its five-color artifact plan too cumbersome.

A colorless 4/5 for six is playable, and surviving to copy a later artifact creature or Equipment provides legitimate rare upside, not immediate impact.

Could be wrong if Artifact density, format speed, and removal are unknown; insufficient qualifying spells would reduce it to expensive filler.
