Good
1) as said earlier i feel that the Inzektor's ability to equip and prevent from destroying (Inzektor Ant) or can target cards on the field (Hornet)
2)Also another good thing about their abilities is their ability to grow a level, which will make it easier to get XYZ on the field instead of having to use other effects
Bad
1) As stated facing a gravekeepers would be an immediate KO, because of not being able to pull out your graveyard so you will have to rely mostly on equippin from hand.
2) Also if someone can get shadow-imprisoning mirror or skill drain, kiss your chances of a comeback good bye
