Thoughtweft Charge

Thoughtweft Charge is a tribal payoff that only earns its slot in dedicated Kithkin builds, which narrows its relevance across every format. In Commander, Kithkin tribal decks are uncommon but exist, and a wide board of small creatures can make Thoughtweft Charge a legitimate alpha-strike enabler — vigilance keeping your whole army untapped after combat is genuinely relevant in a multiplayer game. In 60-card formats like Modern and Pioneer, Kithkin aggro is a fringe archetype at best, and a sorcery-speed pump that requires tribal density rarely makes the cut when one-mana options exist. Legacy and Vintage can theoretically run it, but no competitive reason to do so presents itself. Oathbreaker could find it a home if a Kithkin-themed planeswalker commander ever takes hold, but that's a narrow ask.
