Scourge of the Skyclaves

In Commander, Scourge of the Skyclaves regularly enters as a 15/15 or larger by the midgame — four players means at least one opponent has taken damage, and the card's ceiling scales directly with how aggressive the table has been. Modern and Legacy have run it in Death's Shadow shells, where the pilot deliberately shreds their own life total to land a massive threat on turn two or three alongside Shadow itself. Pioneer is the weakest home; the format's aggressive decks don't reliably drop life totals fast enough to make Scourge a consistent threat, and the lack of fetchlands limits the self-damage infrastructure. Vintage has the raw speed to enable it but rarely needs a two-mana beater when the format ends on turn one.
