Goblin Cratermaker

It can answer artifacts and some colorless creatures, but Haywire Mite (73) is far more efficient artifact hate; Cratermaker's creature mode rarely closes that gap.

Could be wrong if An artifact-heavy metagame or a red creature shell that values the sacrifice body could create a real sideboard niche.

Legacy's cheap interaction makes a two-mana 2/2 plus activation a poor answer; it is around or below Erode's 30-level narrow utility.

Could be wrong if A target-rich colorless-permanent metagame, especially alongside meaningful Goblin recursion, could support a niche role.

Goblin tribal can value a tutorable, recurrable body that doubles as artifact interaction, but two damage and one-shot removal are low impact in multiplayer.

Could be wrong if Its adoption depends on how much a deck can tutor or recur it; ordinary red decks have stronger direct artifact answers.

A two-drop that can trade for a small creature or destroy an artifact is solid flexibility, though sacrificing the 2/2 prevents it from being premium removal.

Could be wrong if Unknown artifact density, removal, and creature sizing could make either mode much better or nearly irrelevant.
