I got 2-0ed by Serprex in my only match, but here's the 5 I had (numbered in order of building)
Deck 5 (790 cost): this was the deck I played in game 1 against Serprex, but I lost when I didn't draw any Graboids in the time it took me to get to 13 cards in my deck.

Deck 3 (786 cost): Played this in game 2 and was stalling out hoping for my 5th fire bolt (had 4 in hand and about 50 fire quanta), but never got enough quanta or bolts to end it, and the poison on me ticked me to my death.
