You're the only one who talks about 80 cards there, m8.
I'm not saying a word on it here since a long time if you pay attention : I'm just playing it very very agressivly, made it evolved and explained it in french on R4G so I'm precise enough with explanations / math, talked about it irl with some very good players there and that's it. Having fun. I play in 78 and still win most of my games, so...
47's not a big deal, especially if you play agro. If you play control, I guess you'd play 45 but to me...
If there only one ID in the whole game that EV / consistency / deck length have a lot less influence on the deck's perfs, that is MaxX and nobody else.
So 45 vs 47... I'm more in the 45+47 camp, tested
Since Stimhack fears and laughes about exploring this / no larla, NP, do your stuff, I'll play mine and won't bother.
