May Strixhaven League Weekend Historic Rules Change

May 04, 2021
Wizards of the Coast

Since the release of Strixhaven: School of Mages on MTG Arena, several updates have been made to address bugs and rules issues. However, one interaction is currently still live that would potentially impact Historic decks during the upcoming May Strixhaven League Weekend, taking place May 15–16.

We are aware of an incorrect interaction between transforming double-faced cards (such as Azcanta, the Sunken Ruin and Legion's Landing) and cards that care about devotion. Mana symbols in the casting cost from the front side of these cards are incorrectly counted for a player's devotion when the land (back) face of the card is on the battlefield.

To remove the possibility of bug exploitation, the following 11 cards are suspended from Historic use by MPL and Rivals League competitors for this League Weekend event only:


  • Arguel's Blood Fast
  • Growing Rites of Itlimoc
  • Search for Azcanta
  • Legion's Landing
  • Vance's Blasting Cannons

Rivals of Ixalan

  • Hadana's Climb
  • Journey to Eternity
  • Path of Mettle
  • Profane Procession
  • Storm the Vault

Core Set 2019

  • Nicol Bolas, the Ravager

These cards specifically encounter this incorrect interaction, and none of the modal double-faced cards from the past year (Sea Gate Restoration, Shatterskull Smashing, Kazuul's Fury, etc.) nor colorless double-faced cards from Ixalan and Rivals of Ixalan (Azor's Gateway, Treasure Map, etc.) produce this interaction.

This suspension is not enforced in-client and does not apply to ranked play and events in MTG Arena—strictly for league competitors for their participation in the May Strixhaven League Weekend.

The MTG Arena team is currently on track to have this interaction corrected ahead of the Strixhaven Championship, taking place June 4–6. Competitors in that event with questions may contact us at

Any player that encounters a bug or other rules issue with MTG Arena can submit it through the intake form to let us know.
