Just thought of some moves had to share them!
Stamina: increase all active arks speed by 10%. But can be stacked until at 50%.
Just thought it would be a great tactical move. Numbers might need fixing though.
Life swap: can swap the percentage of life one ark has with another.
Confusion: like in pokemon confuses a ark and makes it likely to hit its self. Say 40-50% of the time
improvement: increase the rank of all monster on the field including oppositions by 1. ie. a-b a-s and so on.
Any thought are welcome.
