EXPLORER FORMAT

WHAT IS EXPLORER?

Explorer is a new digital experience on MTG Arena – a true-to-paper, non-rotating format featuring all cards legal in the Pioneer format that appear on Arena.

  • Minimum of sixty cards
  • Maximum deck size – 250
  • Up to seven cards (best-of-one) or fifteen cards (best-of-three) in your sideboard
  • Cards that only exist digitally are excluded from Explorer
  • Explorer is managed just like a tabletop format - cards are not subject to either rebalancing or suspensions.

With the exception of basic lands (Plains, Island, Swamp, Mountain, and Forests), your combined deck and sideboard may not contain more than four of any individual card.
