There’s a digital TCG which is almost identical to MTG called Eternal. It’s free on Steam and mobile. Recommend you check it out and see if you like it. I personally think it makes much better use of the digital medium than MTG arena, which often felt clunky due to the way the rules had to be ported from tabletop.
I wish there was a decent alternative to MtG. D&D has about a million (better) competitors, but MtG doesn’t have anything that I’m aware of.
I’ve honestly toyed with the idea of making my own CCG/TCG just to jump ship.
