A random package of multiple small surprise combos:
The Hood -> Viper, leaving the Demon for Moongirl to copy and play in turn 6.
Zero -> Titania for a stable play, or just Titania to jump to occupy a slot on the other side. Titania is a very good card for Moongirl to copy and play in turn 6.
Bishop buffs quite some in turn 6 when it works. Mysterio buffs Bishop a lot, so copying them with Moongirl is great too. The fake Mysterio could be sent to opponent for blocking with Viper.
Next, Wolfsbane is easily a 3-5 or even 3-7 given there are a few 1-/2-costs.
Moongirl copying She-Hulk / Wolfsbane are also great, skipping turn 5, and they could go on turn 6 for surprises.
Rhino and Cosmo are just tech cards to fill gaps, with Rhino more for unlocking locations, Cosmo for general shut down.
