Really I don't care about siding or not in a given card game. I will play with or without depending of the offocial decision.
But many people have a wrong vision of the sideboard, or specificially, player have for me a strange vision of the sideboard.
SideBoard is really part of your deck, and must be taken into account during deck conception, just you have 0% chance to draw a card from your sideboard during a game.
Sideboard is allowing you to deckbuild during a game, I mean which CCG or LCG player does not like to tweak his game? Sideboard just allow you to tweak during round.
And moreover and because of the way you take for your argue, who can say "I am able to counter any strategy with a good probability", please make me dream, show me that list :-).
I agree that sideboard must not allow a player to change the "spirit" of his deck.
And I also agree that if in each order/destruction deck, side cards are the same, sideboard is less pertinent.
even hugely benefited from it from time to time (Raw Deal used to have a card called Censorship Match which meant you could specifically name a card and neither player could play that card. Funny enough, knowing the key cards in your opponents deck kinda helped with this and much scouting went on at some Raw Deal tournaments)
