There’s a bug affecting Heraldic Beast gryphon again. As you can see from the images, I have exactly four monsters on the field, and one of them is the gryphon. However, if we look at the Extra Deck, I have two versions of Heraldry Crest that can be summoned. One requires exactly four monsters, the other five. Heraldic Beast gryphon has the ability to count it as two monsters, so in theory I would also be able to summon the Heraldy Crest form, which requires five monsters.
