Magic: The Gathering

I haven't played it much, but it really interests me as say a cube format where each cmc cardpool can be curated, to eliminate the problem it had on arena or mgto or wherever for a while of it basically being a race to zacama.

It really would require some detailed understanding the cardpool, and probably a wealth of creatures with activated abilities that cost mana for the decisions to be very interesting, so I do feel like you probably need a dedicated playgroup who is interested in that specifically for a while before you are going to get really interesting games.
