Hey here is a good suggestion for a skill.
Randomise: Upon attack uses a random skill between Strike, heal, enfeeble, Protect or weakon.
There could also be a randomise 2 for better move effects nad augment could add to it.
My other idea was this
Upgrade: after each skill use i.e Strike, heal, weakon, enfeeble or protect the move could add a plus one just like beserk but on skills
Ok, this is my last idea
Burn: Upon attack the allied assult card deals continuous damage to the 3 enemy cards around it. (Pretty much swipe and poison combine)
Ok, seriously last idea!
Convert: if an allied assult card has the skill convert and destroys an enemy during its hit then the enemy will be converted to the allied side witht the same ammount of health it had before it was hit with convert, it could also have its wait go to 1 so it becomes fair.
Hope you guys like my ideas, any questions pm me.
