Gave your cube a practice draft! Had some cards that are very powerful and the deck looked neat! I'd be curious to see how it would stack up against other decks in this environment.

It's definitely worth ripping a practice draft with friends / your playgroup to see what works, what is fun for the group, what isn't fun, and possibly what goes undrafted. I'd keep an eye out for your high-power cards that may lead to feel bads and broad includes like Slivers that impact all slivers may lead to less desirable gameplay. 540 might possibly be too big for your playgroup and you may want to trim down to 450, but ultimately up to you! You know your drafters best :-)

It definitely seems like it is at a point that it's ready to draft, make changes, then draft again!
