As a Magic player (since 1996) and Go player (since 2004) and also deep learning scientist, the main issue with Magic is modeling the game. The interactions and exceptions are really numerous, I expect Magic Arena and Magic Online are a mess of spaghetti code. For go modeling basically you have in input an image of the go board, and for DOTA an image of your screen and the action you have are "limited" and do not change wildly depending of the state of your screen (except if you're dead on Dota).
