That's just because Ryan Yu is amazing and the rest of the attendees got caught lacking. As much as we would love for every new support card to be the best card ever and change our lives, the deck's still going to be gimped as long as it has all those "can't have any monsters in your MMZ" restrictons.
The day they release a set that replaces all the current toolkit spells with ones that let you cast them so long as your MMZs are empty OR you only control Sky Striker Ace cards, then we'll see Sky Striker actually being tiered again. We can only hope... it'll probably take 6 years though
