They were way too good in a format with down-tuned removal suite. I also think this format needs slightly more Open Fire type cards. I'll ponder how I can provide these without cutting into support for Flashback-matters.
Also, I've realized this is my "live the dream" cube. I'm wondering if there are ways I can implement some amount of jankier cards in here.
To do: add more fetchland cycles
WIP; adding more interaction with the hope that my main themes won't be diluted
Plan to add more soft removal that trades evenly with Aura'd creatures, and hard removal that is more costly (3-4 CMC range) than the Aura'd creature. Playtesting revealed too much battle-cruiser for my tastes.
