who cares about raids anyway?
do you think they would sell if there where no treasure cards inside?
its something original in the world of tcgs but thats all, the more cards come out the more difficult it will be for r&d to develop a ballanced and challeging game expirience, if they failed allready there is no hope of them getting it right the next time
the card pool availible to players has all the awnsers so maybe they need to make a raid that has threats wich are more difficult to awnser, like uninteruptable abilitys or new treats in the form of new card types (because only ability, ally and equip can be interupted)
allies can be called fiends or whatever, they can enter combat and recieve combat dmg and maybe be protected against, but cannot be awnserd with cards that have an effect on allies
abilitys can be called spells or something
it gives r&d a chance to make raids a entirely diffrent format in wich they design the rules for to make sure that no crazy constructed combos ruin an otherwise enjoyable challenging game
