神器 ~武具
當分靈挽具進戰場時,派出一個0/0,綠藍雙色的分靈衍生生物。在其上放置X個+1/+1指示物,並將分靈挽具裝備於其上。
每當佩帶此武具的生物攻擊時,將其上的+1/+1指示物數量加倍。
佩帶

If you put Fractal Harness onto the battlefield without casting it, or if you choose 0 as the value of X, the token you create will be 0/0. Unless something else is raising its toughness, that token will enter the battlefield and die before you could take any actions.
To double the number of +1/+1 counters on a permanent, put a number of +1/+1 counters on it equal to the number it already has. Other cards that interact with putting counters on it will interact with this effect accordingly.
