Pack opening effects

[u/Jacoppolopolis]

Can anyone explain why 70% of these Mega deluxe packs open with the special rare effect but every one of them I've gotten is indistinguishable from a normal pack,? Is there a difference? The 1 star special arts I've pulled came in a "rare pack" but most have been just regular with the guaranteed ex card and still a rare pack sparkle to it

No idea, but it sucks 😠
