Kay, tested that Mummytal I proposed earlier...and I see where the problems are already. There's just not enough
produced to make Bone Wall AND Fractal Mummies extremely powerful. I went back to pika's original version with another Pend to make up for the additional Mummy, and I found that the AI sometimes got lucky hands and Deflagged everything I could play (and then other times not drawing a Dim Shield causes another issue). Thus, I'm using a version with 6 Dim Shields. It wins almost every time...
But.
Taking a view of this from the enemy's perspective, I'm sure they're going to assume that we're running Bonebolt and NOT Mummytal. Therefore, they will have 0 hesitation in Deflagging an Arsenic thrown out early and will play their creatures as fast as possible to scale over Bone Wall. Unless we get quanta screwed, I'd imagine this deck would trump easily...for the first round at least. In the second round, they'll have a very different tactic to defeat us; they will purposely hold Deflags and try rushing us at the last minute which has me a bit worried since it will undoubtedly catch us off guard. Bone Wall prevents this, but decreases the overall winrate...
I'm still leaning towards a Bone Wall variant, but maybe I'm overthinking all of this...pika, how do you feel about this?
