Are both your lists fully done? Lands and all?
I have crafted a couple decks as well, except for the lands (I still need ~10 rares for lands). The decks are mostly fine without them, albeit more inconsistent. And while everyone was F2P the decks were FINE.
Now, my decks are from the old meta and can't hold a candle to some of the new decks. In order for me to pivot to a more viable list, I have no choice but to spend money or take my licks until I grind ~10 rare/mythics min for a new deck. My main gripe is that I have no choice in this matter.
And I know that Dominaria JUST came out, but still, with dusting, I could at least adjust to a new meta instead of just losing against certain decks by default. Is this how the game will always be when a new set comes out? Is MTG:A going to be eternal? When my cards rotate, what then? (I know this is still far down the road, but it has valid implications currently)
