In the first iterations of my cube I've tried to make madness a thing. One of the problems with it is that it's best when played on curve (T2 outlet into T3 wurm). This requires a huge amount of consistency. You definately want a format where a 4/4 is not too easily outclassed. A problem with madness is it's swingyness. A Bolt with upside is great, but 3 dmg for 1RR is not.
You'd probably want a slow format with lots of cycling and other graveyard shenanigans. The lucre cube if you wish. It would make it so that playing a madness wurm on T3 is powerful and applies a lot of preassure and playing one off a looter on T6 would still have an impact(as it effectively draws an extra card)
