Illegal cards are being played in the standard format and that needs to be fixed.
Somehow players are using illegal cards in Standard Ranked. Not just tutorial cards (which have all rotated out now), but I’ve seen M19 cards too. MTGA either needs to fix this, or have both standard and historic ranked options. Why should I continue to support arena when the game does not adhere to the rules of the standard format? Only cards that are still within standard rotation should be playable in a game mode named “Standard Ranked.”
[Edit] Correction, there is a Historic ranked, which further emphasizes my point. The ability to use historic cards in standard ranked needs to be removed.
