Ironically Magic is already set up Perfectly for an in-universe version of people just playing the game. Its what planeswalker duels are.
Your deck is your mind
Your hand are the immediate thoughts that one has in the middle of combat
Lands are you drawing upon ones mana bonds to in universe lands via memory
Creatures are copies of people, monsters, and archetypical, concepts made out of Aether created by the Planeswalker
Spells are Spells
and so on

A planeswalker duel would best be mechanically shown as a speed chess style match between two players and vice versa a version of the irl game being shown in universe would be a match with all the turn taking and direct commentary on most the plays cut for momentum action momentum.
In that the closest relative to a MtG show wouldn't be Yugioh, it would be Chaotic.
