Game state : I use advanced heraldry art to summon Leo and Gryphon from my GY, my opp let it resolve. Problem : During resolution of advanced heraldry art, i can’t summon Number 69: Heraldry Crest, an Xyz monster that requieres 3 Level 4 monsters as material. I do only have 2 monsters however Gryphon which is one of the monsters im using says it can be treated as 2 Level 4 for the summon of an Xyz monster that uses 3 or more material so Leo + Gryphon are valid requierment to summon number 69 but I am not able to summon it dispite heraldry art not negating the effect of the monster during the xyz summon.
The card data base says that I should be able to summon Number 69 in this scenario Card Database
