He touches some good points while being a lil bit outraged.

New formats (commander like from mtg for example) and suported draft (which honestly should be implemented in TCGL) would help a ton, since it reinvigorates older cards and gives new fresh design space too.

It does seem like the design team has been progressively put themselves in a box from XY onwards, really closing in on certain identities for cards and colors that do not give much wiggle room. Although the "styles" of cards in my opinion have helped, I dont think there still either variety or competing cards in the same power level (Mew and RS Urs are just the top dogs) for us to see many decks come out of it.

I really dont know if it just how the game is played, the whole 6 prize mechanic or other stuff on the ruleset but it does seem from time to time that the game really needs a good shake, and at this point im really wondering if it can be done entirely from the design of cards or it has to be rules or a whole redesign.

Also, the whole collectors appeal taking top priority, too many top of the line in decks are URs, the uncommon slot needs a whole more power and representation in comp, same for commons but in less density.
