I agree and i noticed that when you go online on this topic there is a large number of comments saying no there is no cheating and total denial of it, Because they want to retain the ability to do it often.
Don't humor the cheaters, write down names and who is legit or not, don't give any time to the cheaters
they will eventually die out because they wasted all that time to mod and get the deck and Rare's and then no wants to play them removes the steam, like who could show off to then, sparky?

This is gonna sound bad but, if they remove the ability for players to be able to enter codes and unlock cards at new account creation, and force people to work for their cards with preset decks, it would discourage those cheaters to not want to keep creating fake accounts--- this locks them in so that they would be more willing to spend money, which then if they cheat they lose the money and hard work making it them avoid even more. Yeah, it could seem like pay to win but as long as you allow others to work towards their favorite deck, it's more of an experience of achievement and make sure what they win is just as good as what people buy is great, but allowing players to use wild cards helps in this, so it's not a terrible idea, there are way to make cards you want. just need to work for them. but if you can just create and account and unlock cards, over and over, your not working towards anything and causing nonsense for the true fans and They one goal in mind and that is destroy the player base and ruin the game with cheating so the game will die, its almost like terrorist, they work there way in the game with no intention to make it better or enjoy it but to make others hate it and not want to play it, and shady companies pay these people to do it, example all the Chinese names of players that should not even be on our servers says something... is the game dying?

one more thing, i am starting to think there are premeditated bot matches. When you log off mtg arena after doing all objs, best beileve when you get on tomorrow the first person your gonna play is someone youve seen already the days prior and players are starting to figure out that just based off their deck they are playing who they will most likely pair within the future. It lines up players to you like an appointment, not random at all it seems

I am also a veteran of mtg and we both know when something is not right, once you get passed 3 to 4 games of a new player your lured in to liking it and then the anxiety and stress comes in, I started to realizing the need to smoke a cig or something during a match or after a frustrating one
