1 mots per season is reasonable idea. I hate present MOTS set up and usage. We know nothing about his power, for example i lost game in cup against team who just join GKO month ago, he played with MOTS, i have 130lvl strongest team, it was a tight game, but i lost the game in extra time. My next match I was one who played with mots (against strong team, much stronger than the one i lost, but weaker from my team) and i won the game 1-0 with much efforts. If someone ask me, i will "kill" the mots option in GKO, and find some other solution for close the gap between big and small teams.
