I intended to simply outrush a Dim-stall strategy given the upgrade advantage, Death rushes strongly, and Poison in a no-Purify-allowed environment... I mis-judged that quite a bit.
Yup - the illegal deck game 2 was HUGE. Also, I should definitely (20/20 hindsight) started repeating the Charger deck before I was at 4 losses.
My bans also put a BIG hurt on a lot of common death decks such as Bonebolt, Pandebonium, Wings+Recluses, Speed Poison (chrys/poison/freezing), and the light stall stuff. Left the Dims alone and neglected to in-match adjust quick enough.
/I am vanquished!
