Infinite Blade (無限刃, Mugen jin) is a new ability that was released in BS33.
Spirits with this ability have the following effect:
- (Your Attack Step) While there is (Soul Core) on this Spirit, this Spirit can target attack one opposing Spirit or Ultimate. At that time, this Spirit does not become exhausted.
This means that unless you choose to attack the life, this spirit is capable of making unlimited attacks, so long as it doesn't get destroyed in the process.
Currently, the only card with this effect is The MasterSwordsmanDragon Samurai-Dragon-Amatsu.
