Whats interesting to me is that Commander pre-constructed decks were intended as a one-off, but obviously exceeded expectations and became a mainstay (to say the least)
Heres a quick reference table for you on the minimum and maximum number of cards for each format
You start with 25 life instead of 40, and games are faster
Broken Dreams "Powered" Cubes get their name from the inclusion of the Power Nine (Ancestral Recall, Black Lotus, Mox Pearl, Mox Sapphire, Mox Jet, Mox Ruby, Mox Emerald, Time Walk, and Timetwister), and other cards of similar power level
Sadly far too narrow to include in the main drafting cube but one of the few demons that performs a specific role rather than just being big and demony
Cards that manipulate the top of your deck allow you to decide which card youll draw next
