Might as well share my main deck, is not like there's proper multiplayer or a competitive scene (YET?). I saw a similar one in the Ci-En website years ago but with the new additions and some labbing is much more consistent than that version.
CS005=3,CS008=2,CS011=3,CT013=3,CT024=2,CT025=2,MC001=3,MC004=3,MC006=3,MC008=3,MC022=2,MC023=2,SC007=3,SC014=3,SC101=3,p=SC007,t,n=Paizuri Exodia
This is a combo strategy with the sole goal to paizuri the opponent into oblivion and nothing else. No minions, no other sex actions (unless really needed), only booba. Just be aware that you have to pull out the wincon as quick as possible, since you have zero defenses and things like several enemy SoPS can easily brick your hand if you take too long.
Strategy:
Cheerleader is the main piece of the combo, as your goal is to draw either Welcoming Invitation or Hypnotising Ring to turn your paizuris into direct attacks no matter the state of the board by triggering Cheerleader's tempation every turn. Practically most of the deck is cheap draw effects to dig them out. Be aware that Time Walk won't trigger these effects, so only use it to stall or if the opponent has no minions.
Depending the deck you're facing that should be enough to win, but afterwards you can go beyond that with Devil's Bargain to deal massive damage plus ton of energy (Specially if you stack both together). Usually the turn you play Bargain if you manage your paizuris properly will lead to a win (e.g. attack with the weakest paizuris for energy) but otherwise Purity Field is a safety net for the next turn and not be the one being paizuri'd to death (nice). The demons' double paizuri won't increase damage with a breast increase (in one or both), but with Bargain you can instantly unseal their effects plus make the opponent draw enough addictions to win with their alternative wincon. Also breast increase+double paizuri being the best scene in the game, but you are reading someone who loves tits so yeah.
Also remember that Milk Demon's vaginal attack can generate the Breast Slave Crest if unsealed, also making paizuris into direct attacks. Is extremely rare to trigger since you'll most likely be winning at that point and given is a non-breast attack you'll most likely, due lack of a better word, fuck yourself. But if you fight a deck with tons of negation and/or card removal it can come out sometimes.
Sorry for the big wall of text for a niche hentai game but as a Combo Deck needs to be explained. I didn't touch the game for a while and had to relearn some technicalities about it. My original idea was to aim for the Breasts Save the World wincon, but given Pursuit effects won't give additional counters is better to just go full paizuri aggro. I actually fought this deck in the online mode and the CPU can't figure out what to do but aim for the SoPS wincon and nothing else.
