Kyuzan Unveils 'MUSHInomics with MUSHIKING'

On November 11, 2025, Kyuzan, a cutting-edge startup based in Shibuya, Tokyo, officially launched its highly anticipated blockchain game titled 'MUSHInomics with MUSHIKING.' This vibrant card battle game, licensed by Sega, makes use of the beloved franchise, Bug King, allowing players to engage in thrilling battles and collection activities.

Game Overview

'MUSHInomics with MUSHIKING' is not just a game; it's an expansive journey designed for PC and smartphone web browsers. Players will dive into a world where they can collect unique bug cards and construct powerful decks. This game is part of a limited-time seasonal event set to last approximately six weeks with the inaugural season kicking off from November 11 to November 18, 2025.

How to Play 'MUSHInomics with MUSHIKING'

The gameplay of 'MUSHInomics with MUSHIKING' is centered around collecting cards and strategic deck-building. Here’s how it works:

1. Collecting and Minting Cards

To begin your journey, players must gather essential bug cards required for battles. The cards can be acquired through a gacha system where players can spend MUSHI, OAS, or pOAS tokens to mint them. Additionally, players are entitled to one free gacha pull each day.

- Card Characteristics: Cards come in SBT (Soulbound Token) format, meaning they cannot be transferred. Their validity lasts solely within the season they are associated with. Players will encounter various parameters such as HP (Hit Points), favored hand (Rock, Paper, or Scissors), special moves, and attack power, providing diverse strategic options for battles. Furthermore, cards with higher rarity may possess multiple special traits which offer score bonuses.

2. Deck Construction

Once players have collected enough cards, they can start constructing their decks:

- Deck Size: Each battle deck can contain up to 10 cards, and players must designate one card as the 'Main Card' that will be active during the battle.
- Strategic Bonuses: Each card carries specific traits, and if players include three or more cards sharing the same trait in their deck, a bonus score will be activated. Discovering the optimal combination of traits is crucial for effective deck construction.

Attribute Tokens

The game introduces attribute tokens corresponding to the battle hands—Rock, Paper, and Scissors. These tokens serve to enhance player performance by boosting battle scores.

1. Overview and Acquisition of Attribute Tokens

Attribute tokens are individually issued on YUKICHI.FUN for each battle hand. Players can obtain them by swapping MUSHI.
