Since Drummernaut and Panpaca, Jaga are of different houses, it takes at least a turn to set this up.

No offense, the problem here isn't with the rules, but it's with the fact that you didn't recognize a combo like this was possible. That's not a call to change the rules for Skirmish, it's a call for you to take note of how powerful Skirmish is with the new Brobnar cards and deal with it better in the future.

Yeah this isn't even the most powerful combo with Drummernaut. I used it, Ganger Chieften, and Into the Fray (along with some other brobnar creatures) to clear the opposing board, then loop Ganger repeatedly for like a 10 aember turn (Foozle was on the field and I used ganger with her on the last time for +4 aember).

Did your opponent follow the rule of six? Just covering the bases here.

Just FYI, I did the same thing without Skirmish. I had massive Brobnar creatures (any of the following Drummernaut, Ganger Chieftain, Lollop the Titanic, King of the Crag, 2 Groggins, & a maverick "Lion" Bautrem). We played a sealed and I did this in consecutive games. Didn't win either, but didn't lose any of my giants and removed all of my opponent's creatures.

This set seems a lot more susceptible to board wipes. My first sealed deck (which won me a tournament and a box of Call of the Archons ) had Total Recall, Carpet Phloxem & Ploxem Spike, which I used more than once to clear my enemies' line.
