I've been saying something like this for a while. The issue is that you're essentially playing an eternal format as the only one, so Konami's problem is that they need to consider all existing cards before they print something, because otherwise they'll make unintended synergy with something they printed a decade ago, which is exactly what happened with Substitoad.
So Konami has really leaned into archetypes, which were already present in the game but have obviously gotten more prominent because archetypes are mostly self-contained and can be adequately hamstrung by banning linchpin cards, which conveniently puts them in a position for planned obsolescence to push the next pack's archetype.
If Konami would have tournaments and recognize formats that aren't Legacy or Vintage (essentially), they could break the cycle. It would require them to reprint stuff like MST, Solemn Judgement/Warning or whatever, but that's easily handled by making stuff like reprint packs that never rotate out.
This alone wouldn't solve all the problems of the game but it'd make a decent dent. You could stop the power creep. But I really doubt that Konami would do it, considering it'd be a tacit admission that Magic handles their formats and banlist better than they do. They'll just milk the game until it dies because most YGO players are the same kind of whales that pay hundreds of dollars for lootboxes and facebook games.
