September’s Arena Powered Cube update makes four previously unavailable cards collectible on MTG Arena: Comet, Stellar Pup; Hymn to Tourach; Urza’s Bauble; and Vindicate. They are now legal in Historic, Timeless, Brawl and Competitive Brawl.
The change matters beyond the temporary Cube event. Urza’s Bauble gives artifact and graveyard shells another zero-mana cantrip, while Hymn to Tourach adds random discard to black strategies. Comet offers a new planeswalker and Brawl commander, and Vindicate adds broad permanent removal.
Wizards also added new cards to the client specifically for Arena Powered Cube for the first time since the format arrived in September 2025. Cube prize packs additionally gained alternate artwork for Brain Freeze, Daze, Force of Will and Library of Alexandria.
