Kingdom Key- Only Player/light Cards can use this card. if you equip this and win a challenge, subtract your Player Card lvl from your opponents player card lvl. Subtract That Difference from your opponents HP. if the difference is in the negative than subtract 0.
My first question is can equipment cards be played on your opponents player card? ( i know no one would want to but its just a question id like to know the answer to)
2. the wording is weird for me so say im sora and hes ansem i equip sora with the key and challenge then win would it be 10 - 1 or 1 - 10? i think its 1 - 10 but im iffy on it because they word things tricky. if its 10-1 then **** this card can beat ansem with one challenge. but i dont think it would be that broken.
Bonus question.does the uniqueness rule apply to dark/nobody cards when played as friends?
