unlike most OCs in battle, Morphic Matters "power" scales depending on the opponent, and though there are no set rules on a maximum power a character can have, if it seems unfair, Morphic Matter will most likely play unfairly as well.
because of the scaling effect, your character gets to deal the first strike (but if you wish to reserve the first strike for MM, the difficulty will start low, and increase) https://scratch.mit.edu/projects/634428057/ (some info)
