Arena Powered Cube adds Splinter Twin and new cards for its October run

Wizards dates Arena Powered Cube October20–November10 with22new-to-Arena cards and16new artwork versions.

Wizards of the Coast has detailed a substantial October update for Arena Powered Cube, scheduled for October 20 through November 10. The rotation brings 22 cards newly implemented on MTG Arena and sixteen additional artwork versions, alongside cards from Reality Fracture. Through the Breach and Walking Ballista are

among the additions discussed in the official overview. Splinter Twin and Kiki-Jiki also enter the experience, with Wizards explicitly watching how players respond to combos that require many repeated clicks. The cube remains a 540-card singleton format, and its phantom drafts do not add drafted cards to a player’s

collection. This is a new rotation and card-pool revision, separate from September’s addition of monarch cards; the announcement’s dates alone do not confirm an individual player’s client has updated. Official source. Image credit: Wizards of the Coast; official Arena Powered Cube article artwork.
