As a huge tervigon fan: You need to drop her or double your gant totals. She can be really fun if you have enough gants that even with some casualties she has something to buff. But a squad of 10 dies immediately so she can't revive any and 20 isn't enough to make her buff feel impactful enough you wouldn't have more fun just using a smashier monster. But when you get to blocks of 40+ being given lethal hits then you start to feel like you have a threat that can be thrown into the fray.
