Amane and Kazuki were close friends back in their youth. After a tragic accident, Amane was left all alone to fend for herself. Years later, she managed to form a family with the other girls of her new school acting as their pristine and slightly perverted older sister.

The main combo works with the three cards above. Essentially, the goal of the deck is to recycle the climax and constantly apply pressure to your opponent by overwhelming them with soul damage. The three cards work in a chain as the Amane (left card) is an assist that lets you pay three stock to salvage the two soul climax. The center card, Kazuki has a climax combo that lets you stock two Grisaia (グリザイア) characters from your waiting room if your opponent cancels the soul damage dealt by this card (climax on the right). The power effect is a nice addition, but the primary goal of this card is its climax effect.
Ideally these two cards will combo and deal significant chunks of soul damage, or GRI/S72-030R‘s damage will cancel and you gain large amounts of stock. Either way, during your following turn, your opponent will likely be in some sort of chaotic state.

Since the deck builds an enormous amount of stock, the question is how exactly do you use the stock advantage to defeat your opponent. The answer to that depends fully on you. I’ve placed a couple finishers above that are examples of finishers that can utilise the excess stock from the two soul combo.

Regardless of however you build the deck, it is crucial that you have the means to recycle your resources to regain your GRI/S72-030R. The two soul climax returns to your hand easy enough as is thanks to GRI/S72-035U so getting the climax is less of an issue.
The set also has the events above which effectively perform the same goal in different ways. They will more often than not be used for their backup utility rather than on your turn. The point is the two events save your GRI/S72-030R, thus allowing you to recycle and reuse the combo again.
Luckily enough, the set does have access to two different climax swappers. You can choose between the two or run various numbers of both. Paired with the treasure trigger climax, these cards are very efficient at their job of recycling the two soul climax back to hand. Their purpose is just to reduce the costs of regaining the two soul climax by offering an alternative cost rather than paying the hefty three stock cost for GRI/S72-035U.
Because the deck profile only relies upon the three cards at the top of this post, I don’t really have many suggestions to provide other than the cards already mentioned. There are many ways to build this deck with the three card combo skeleton just acting as its advantage engine. I will suggest the card above as it is a great finisher since it fulfils its own power condition and doesn’t require a climax to do its effect. Its main costs are the stock values, but given how much stock you will theoretically make with this deck, the only real costs are the discard conditions.
Either way, good luck with the deck. Try mixing up the colours. Maybe even make the deck pure green. Let us know and maybe send us some pictures of what you come up with.
