Hmm...

Alvids are a must-have.

I think they're overrated. Although, if you need to finish off a few hit points after Albert, then maybe... In any case, I don't need to craft them, I don't have them.

By the way, sword archetypes (at least those that were before the patch) are a rather vague concept... I've come across builds on the internet labeled as "midrange" that were almost as heavy as my control deck, and other "midrange" decks that turned out to be almost as aggressive as my aggro deck.

So, I might not understand the terms, but it seems like a sword deck is either aggro or control. These are global playstyles, not the timing of maximum power, right?
There's also an early sword deck with a lot of 1-cost summons, I tried playing with that before, and a mid-range deck (which I called midrange). People usually don't play sword decks in the late game.
