this is silly (in my opinion at least), with the amount of lock cards in the format and coming in Ancient Origins expanded will give players the ability to make decks which lock their opponent out from doing practically anything, that along with so many other things will make it a very broken format, cards are designed with rotation in mind, right now people are abusing skyfield/colress for huge draw support but they were most likely only intended to see play together for this short time. I feel like expanded was supposed to stay as side events or day 2's of some competitions, not find its way into the mainstream.
