Well done! That's more like it.
At no point have I advocated the removal of luck from Pokemon. I absolutely accept it's existance as an essential part of the game. Additionally, I've strongly refuted the author's claim that bad starting hands are "unfair." So, in a way, you're "preaching to the chior" about luck and it's fairness.
Nevertheless, in a competitive environment, skill should dominate, generally speaking. In that context, an optional mulligan should not be categorically rejected with irrelavent statements like "go play chess" or false comments like "bad starts are good for the game."
I understand that some games in Pokemon will be won by luck and some by skill. Nevertheless, Pokemon champs and top players are viewed as being more skilled than lucky, wouldn't you agree? If you do, then wouldn't you also agree that something that advocates skill is a good thing, so long as it doesn't destroy the essential elements of luck?
Are bad starts an essential element in Pokemon? I don't think they're essential, but if you do, then I can understand why you would consider an optional mulligan to be damaging to the game.
