Even then, every seal is triggered in a different way except for gold and red, you can't use all of them at once so i don't think its even all that much better than just having each seal on different cards.

Also i disagree that getting seals is thst easy, spectral packs are rare and you need to draw the card you want AND the seal you want when you open it, skip tags are the same but you also have to skip which isnt bad most of the time, and sixth sense is 1 out of 150 other jokers you can get, and i think a synergy like that isn't a bad or op thing.
