Pretty sure it's weak to kidnapping/hypnosis.
Maybe. The AI is pretty weak, it uses squeezers to damage itself, so once Infinite energy is up it is a sure win against the AI. Against a human it might be more difficult.
Thanks to the buff of "Big breasts" "Breastfeeding" got stronger too, as "Big breasts" doubles its effectiveness.
Anyway, here is my variation of the Infinite energy deck:
CS005=3,CT006=3,GD007=3,MC001=3,MC004=3,MC005=3,MC006=3,MC007=3,MC008=3,SC001=3,SC002=3,SC003=1,SC004=3,SC005=3,p=SC003,n=Draw Infinite Energy
"Harapeko Inma" got such a huge nerf that "Breastfeeding" and "Energizer" might be overkill. I do not have "Erotic book of bushes" as 6 energy for the first card draw is too expensive; by the time you can afford it you rarely need it anymore. "Novice Engineer" to counter "Hypnosis Phone", with "Bloomer girl" you can use its ability to turn you played it.
Other than that pretty obvious choices for the rest.
.
The buff to "Big breasts" and the buff to "Devil" also gives you another strong synergy. Use "Bloomer girl" to give yourself Quick and then use the Big breasts ability of "Devil". You get two 2/2 guardians with Quick. Buff those spirits with "Bunny girl" and you can get a strong army out of seemingly nowhere.
GD004=3,GD007=3,GD009=3,GD011=3,GD012=3,GD019=3,MC001=3,MC004=3,MC011=1,SC001=3,SC002=3,SC004=3,SC005=3,TC004=3,p=SC004,n=High Value
"Requiem" is most just in there because I had 1 slot free. Dunno if "Breastfeeding" is better than "Energizer".
