It doesn't really. You're base deck still needs to be able to handle everything. A side deck just allows you to specialize once you know what your facing.

In the case of Magic World, I tend to run more Go to Hell!! than Abra Kadabra. However against Magic World I'd probably like to switch that around to better fight that deck. I don't usually run Destruction, or a low number if I do, but I could switch it in against Danger World and Magic Burn. It actually allows slightly more solid base deckbuilding, since you can switch in your "tech" and keep your main deck more focused.

Then there is also the added element of predicting what your opponent is sideboarding. theres even the possibility of using a sideboard to completely change your deck (it's rare that you can do this, but when you can it is a fun mind game).

I don't have a stake in side board or not. Either is fine with me, but I don't think there will be one in this game.
