Alright, I admit, I wanted this list to be a lot more expansive since we also have many more cards like Ultima, Town Greeter, and especially Astrologian's Planisphere (another crucial component of the new Vivi Izzet build), those that definitely had solid deck entries during the last major tournament event
Ramunap Excavator is a commonly Cubed card that honestly just kind of sucks more often than not
As a cosmic magical gem, it ought to be powerful, but this is downright overpowered
While all of them are a blast to pilot, the first two are the easiest due to Clouds versatile equipment playstyle and Yshtolas fun card draw/damage engine
Most of the rest is heavily reliant on catching up to your opponents who are already ahead, making it difficult to actually get ahead yourself
