Here an idea of an fire based Shaman. Maybe a Shaman is a option to create a creature with typical themes for every color... In that case the abilities name have to change a bit, of cause all other Shamans need to have good abilitynames.
Shaman -- Creature -- 1/2 -- Costs???
mysticism: Pay X+2
Quanta to destroy the target Weapon or Shield. (X ist the cost of the targeted weapon or shield you want to destroy)
Yes, fire have CC and PC, but what you are thinking about this particulary PC on a low HP creature? Any Suggestions?
