Looks like a close one. Usually Pandebonium loves facing Ghostmare, but Daggers, Duck, few RT's and Nymph added on to slow quanta gain for the Pandebonium would be enough to turn this around. 8 pends looks scary, especially when there's draw denial. Was it a big problem?
*edit because I completely misunderstood the question at first and still wonder how that was possible...*
Draw denial wasn't that big of a problem actually, I generally tried to keep a no-cost card in hand and didn't have to discard a single Ghost in any of the matches.
The bigger problem was the 0 pend start (for 6 or 7 turns) in match one and general bottom decking on my side, early Dusk hax in matches 3 and 4 and Pande fails for pretty much every use, it RT'd, PU'd, lobo'd Ghosts and grav pulled them constantly, annoyingly, it still was quite close every time.
