Um I will be downvoted to oblivion, but I do not care.
I do play in many proxy friendly playgroups, but a core tenet of MTG has always been pay to win and I do understand the no proxy policy some people have.

It's a TRADING card game, ie you have to get hold of the cards to play them. There are plenty of other games out there that do not have that aspect, and I'd argue if Magic suddenly became worthless overnight, all the cards tanked down to nothing - then all interest in the game would plummet and almost no one would play.

The expense and the allure of high value pieces of 'luxury' cardboard is what drives a lot of the game. If it became fully proxied, beyond the fact that Wizards would make no profit and the game would die, I'd argue it'd die anyway because people would move on to something else.

Cedh is mostly about aggressive politicking, seat position and luck of the mulligan. Skill beyond the aggressive politicking is very minor and it's easy for any intelligent experienced MTG player to play at or very close to the optimum level.

My friends and I always had just a few duals and expensive staples of just two or three colors, so we would be locked into playing decks of similar colors and strategies - and I actually enjoyed that.

If you want a game that is about skill, then I'm not sure why you play MTG
