As implied by the title of this post, the deck structure of this article will focus upon eight events. Within the set of Kaguya-sama, there are number of cards that carry synergies with use of events and the presence of events in the waiting room. The goal of the deck is to use and manipulate events to your advantage and bring down your opponent.

The deck mainly functions off of two pairs of events and their synergies. The first set of which is shown above. The card on the left is a generic hand filter event which checks the top four cards of your deck. It additionally gives the bonus of bouncing any annoying costless threats in your opponent’s front row. It is important to note that you must always have a Chika present on the field to resolve the event. The Chika in the center synergizes with the left event to deal additional damage to your opponent upon reverse. The soul damage is based on the number of KGL/S79-018KR-KR in the waiting room. It combos with the climax on the right.
The other event mentioned is the card above. This card is essentially a free 3500 power backup that also swaps a card in your level zone with that of a climax from your waiting room as part of its cost (mandatory effect). This is very important as it pairs well with another card shown below.
This card synergizes very well with KGL/S79-045U, allowing you to perform the same effect as KGL/S79-018KR-KR minus the additional bouncing effect to an opposing character. For the cheap cost of a single stock, you can net an additional hand from the top of your deck replacing the counter you just used. However, this card’s use is not just limited to only KGL/S79-045U. Anytime a card is swapped in your level zone, you can do this effect.

These two cards above help KGL/S79-028SR with their secondary abilities. Since KGL/S79-045U puts climaxes into your level zone, these cards can help to remove them and replace them with another card. That would trigger KGL/S79-028SR and allow you to activate the ability and net yourself another hand.

As for the other combo for the deck, this advantage combo above is highly suggested. It possesses a flexible modal ability. With the climax on the right, this card can choose to either remove any cost 0 character in your opponent’s front row by bouncing them back to hand and give itself +1000 power or to give itself an on-reverse salvage ability.

These two cards above are your main means of getting the events to hand besides drawing them. Each of them allow you to discard a card to retrieve their respective events from the waiting room, making it easy for you to cycle and churn through cards in your hand and deck.

The cards above add consistency to the deck. The card on the left combos with the card in the center, giving it additional power and a level. The more relevant effect for this card lies in its second ability of simply pay a stock and tapping to reveal the top card of the deck. If that card is a Shuchiin (秀知院) character (pretty much every character in the set) or an event, you may add it to hand. The card in the center is just a vanilla card, but works well with the card on the left to make itself a strong beat-stick. The card on the right is an assist that lets you discard a card and search your deck for any event. Additionally, once per turn, if you use an event, this card lets you give any character +1500 power for the turn.

The pay-offs for running events are the two cards above. They gain large amounts of power whenever an event is played. With a single use of an event, they both gain an additional +2000 power not including the event’s effects. It is important to keep an eye out for KGL/S79-041C as swapping the climax into the level zone may cause his first condition to fumble in certain conditions.

The three cards above are nice additional options to add to the deck. The Miyuki on the left allows for alternative means of finishing your opponent. The Kei in the center is an early play healer that heals to stock. The Chika on the right is a healer that provides additional soul damage and power to your other characters when she attacks.
As always, I’ve provided additional cards that are good contenders for the deck. Feel free to make any changes as you wish. Hopefully you can raise the mother and son pair of Chika and Miyuki to victory.
