This sounds like a good spell to play when you don't want one of your creatures to die via overdrive. Nice synergy.
It removes overdrive, as overdrive is an active ability.
If I understood the card correctly, you could use it when your overdriven creature reached 1HP (keeping it alive because of the lobo effect), but you could make it kinda resistent to CC, by spending some quanta during your turn. I'm supposing that if I take a creature with 1HP, use this ability (body mass) to give it a temporary buff and my opponent uses CC on it but doesn't kill it, on my turn it will still be alive with 0HP, so I can keep it alive by continuously spending quanta.
You could also do the opposite, using the body mass ability and overdrive on the same turn.
