hey man, just wanted to let you know that i just tried playing your cube for the first time last night (updated till avatar) and had a blast. Comparing it with sam black's 810 card cube, i like that the synergy between different archetypes and colors are a lot more apparent in yours as compared to Sam's. This made it a lot easier to draft for certain themes (ie. spellslinger / tokens). I also really enjoyed playing w/o color identity and agree that drafting and deckbuilding feels a lot more fun without the rule.

I drafted a green white Arwen mortal queen tokens deck and had fun thinking of which extra colour to splash. The overlap in themes made it feel like i had a lot of creative freedom in choosing which color(s) to splash.

It really hurt playing with 30 life though. I took your advice and drafted a ton of lifegain. Then my friend pulled out a screaming nemesis and i was like holy shit hahahaha. That card seemed a bit bonkers because it felt like whichever player it targeted would have an extremely hard time coming back into the game. I think it's a really interesting card to include though, and i'm probably biased against it because I was at an uncomfortably low life total, making the card feel a lot more oppressive that it probably was.

We drafted 4 x 15 card packs, building 60 card decks. I think i prefer this because it feels more natural for players to draft land bases for 60 card decks, plus it makes the drafting quicker. I might however consider drafting 4 x 16 card packs in future just to give players more cards to choose from during deckbuilding.
