- Oct 14, 2022 A player prompted to name a card may name the combined back face, and each player has the right to know that combined back face's characteristics at all times.
- Oct 14, 2022 If an effect moves a melded permanent to a new zone and then affects "that card," it affects both cards.
- Oct 14, 2022 In the Commander variant, a meld card's color identity is determined only by the mana costs and mana symbols in the rules text of its front face. No symbols or rules text of the permanent it melds into are considered.
