@Protoaddict I think you missed my point. If you print lots of Companions, then you will have lots of different possible deck building restrictions. The more possibilities there are, the greater the chance that you can find some companion that requires no or very little change in how you build your deck. Look at what we see today: Lurrus and Zidra in particular are practically free to run. They require very little change to existing good decks.
This is precisely my point. What if it's not a matter of "if" but "which". Companions become ubiquitous and there are enough of them that powerlevel is fairly flat and there is a variety in selections to consider.
No one has issues with every deck having 15 sideboard cards, and that has no deck building costs. It just is part of the game. What if this just becomes part of the standard, base level game?
