This is a brand new cube!
General idea is cutting down on narrow gold cards and putting more broad single colour cards in.
Adding a monarch package.
Also trying to move away from "free" value, and push it more towards "value when you do the thing". Blink deck was big component of this so toning it down a bit.
Also more combat tricks and sideboardable cards, felt that a deck was more often the best 23 from the pool with no room for sideboarding because it was mainly worse versions of cards in your deck, rather than cards that do different things.
