#sideboarding

I've been thinking a lot about sideboarding lately, and I feel like it's become a lazy way to fix decks that aren't quite right. I mean, don't get me wrong, it's amazing to have a bunch of sweet cards to swap in when the opponent is playing a certain archetype, but it feels like people rely on it too much. What's the point of building a deck if it's just going to change completely when you hit the sideboard? It seems like a cop-out to me. I'd rather see people put more effort into making their main deck versatile, rather than relying on a bunch of situational cards to bail them out. Has anyone else ever thought about this? Am I just being a contrarian for the sake of it?
