> With MTG, you have a huge effect from the quality of the deck. Unless you have each player play with each deck, there's no way to de-convolute the quality of the deck vs the quality of the player. And if you did have that data, Elo couldn't leverage it -- you'd need a more sophisticated model to account for that statistical effect.
How well a player chooses their deck is one of the factors that determines how good a player is. You can say the same thing about the other games: I'd probably have a better rating in chess if I didn't only play somewhat unsound gambits, and I'd definitely have a better rating in Starcraft if I didn't only do 2port wraith in TvZ.
