Yeah, sounds like a good time indeed. Narset decks are still not a problem for us to beat, as narset is kinda like Lavinia: a good card against us, but a card that is played in decks that are a very favorable matchup for us. But karn decks are usually bad for us to beat. Too many things we have to answer with taxing effects to make it harder to be answered. It's funny, against bad pilots it's even favorable to us, but against good players my win rate against it is pretty low.
I didn't even have it anymore, I had sold everything I had except for a deck I had named 'weird survival' which became the normal survival to me. Now I think I gathered enough tix to buy this deck back, will surely give it a shot. I'm just not sure how will survival look like with modern horizons and all those cool toys that come with it.
