User summary:
カミムスビ (Kamimusubi) is a middle-ware game, to be used with other Trading Card Games (TCGs). This game is intended to let cards fight each other. You can play Kamimusubi as a stand-alone game, but by adding other TCG's cards as an extension deck, it is possible to produce a variety of play. The cards which are lying idle in your house get ready to fight for a battlefield never seen before. Let's create the strongest deck with your TCG cards!

You play a card from your hand and pay cost and send a character to the battlefield, like in the card game "San Juan". When you pay higher costs for your character, you can put an expansion card on the top of a character card, thereby transform a character itself into an expansion card.

Kamimusubi is a 2-player game and has 36 cards in the deck. Players let characters fight, and the winner is the first player to cause direct damage on their opponent five times.

The game uses artwork by the designer but also free artwork from an open source video game, ジュエルセイバー (Jewel Savior). The publishers of the video game wanted the widest possible use for their work, so turned it into open source. The artists for the video game are listed on their website.

Publisher's summary:
カミムスビは「異なるＴＣＧ同士を戦わせることを目的とした、ミドルウェアゲーム」です。
これ単体でも遊ぶことが出来ますが、他のＴＣＧのカードを拡張デッキとして追加することで、多彩な遊び方を生み出すことが可能です。
あなたの家に眠るカード達がまだ見ぬ戦場を求めて張り切っています。
目指せ、ＴＣＧ界最強のデッキ！

サンファン方式で、手札を捨ててコストを支払いキャラクターを戦場に出します。キャラクターはさらにコストを支払うと拡張カードを上に乗せることが出来ます。それによって拡張カードに変身します。
そして、キャラクター同士で戦闘を行い、先にプレイヤーへ5回直接ダメージを与えた方が勝利します。
