Oops, All Squirrels | Building Your Unbeatable Squirrel Girl Commander Deck

The Unbeatable Squirrel Girl is a mono-green legendary creature from MTG Marvel Super Heroes that may be one of the strongest token Commanders ever printed. She creates a Squirrel every time she enters or attacks, and her doubling ability never taps, letting you activate it as many times per turn as you can afford. This guide covers the full strategy across every stage of the game plus five must-include cards, including the genuinely busted Earthcraft infinite combo.

MTG Marvel Super Heroes prerelease weekend wrapped up June 19 through 21, and the real games have started to reveal what actually matters in this format. One card stole games outright. A cluster of indestructible and hexproof threats left some decks with no real answers. And a handful of overlooked commons and uncommons quietly punched above their rarity. Here's what prerelease taught us heading into the June 26 release and the draft season that follows.

The biggest MTG singles price spikes of June 2026 span the entire market, from cheap Marvel speculation plays to a leaked Secret Lair Commander deck sending Miku, Divine Diva past $70 to a quietly compounding Premodern boom pushing Reserved List staples like Replenish toward $175. Add in the run-up to Marvel Super Heroes on June 26 and the Premodern Price Index up over 22% in 90 days, and June gave finance watchers something in every price bracket to track.
