Hi, just wanted to ask about the main difference between the Esper and Dimir Lurrus Variants in gameplay/gameplan, if there is any.

Are proxies that are printed on regular paper, put into sleeves with normal mtg cards legal for tournament play or would there be some issue with thickness? I've never been able to tell them apart from regular cards in their sleeves while shuffeling but maybe more skilled players than me could so I just wanted to be sure.
