Tower Heroes - Cake Factory [Hard Mode Trio / Make a Cake Collab]

Decks:
P1: Lemonade Cat, Voca, Scientist, Byte, Goblino
P2: Scientist, Voca, Dumpster, Discount Dog, Balloon Pal
P3: Scientist, Voca, Quinn, Maitake, Spectre
Notes:
This was the first time trying the Medium Mode strat on Hard Mode (I'd already beaten Hard with a different much slower strat), so it was good to know that it worked more or less perfectly. As we were just winging it, our placement wasn't as optimal as it could have been.
Medium and easy can be done with 2 people only, using the decks of P2 and P3 and following basically the same steps.
Dumpster will let a couple of enemies go, but the second cake upgrade will take care of most.
Gertrude could have been easier if we'd upgraded another tower like Scientist or Voca (Branch?) earlier. Clutch moment.
More clutch moments starting wave 30, where due to (mini)bosses, you'd surely need to slow down. However, we discussed during match that Frank could have helped with that, getting rid of the minions so the other towers could take care of the boss (in the 'slower' strat I played, a bunch of Volts took care of these).
Regarding the nerfs: Quinn could have helped better if she hadn't been nerfed, both in price and in power. Byte is literal trash now.
Thanks to the friends who helped me figure out the strat.
