Is it passive?
If not, Overdriving Rusted Robot should be extremely fun.
I am not sure what you want to know
The *Twitchy* is passive and cannot be removed.
The way this creature works is as follows: When damaged, it gains Acceleration/Overdrive - as if the spell card would have been used on it. This can be reversed by lobotomizing the creature. However, if damaged again, the effect takes place one more time, without limitation towards the amount of times being triggered.
You could, for example, do all of the following in the very same turn of yours: lobo your opponent's overdriven robot, then use a fire bolt on it (which causes overdrive again), lobo it again and trigger overdrive a second time by using another fire bolt on it ^^
