Nothing much to be said about the startegy: Regular Krawlers with but more colourful plays than regular Krawlers.
Boss monsters are the Beetroopers which are all relatively easy to make in the deck (but usually at the cost of banishing resources from your GY) with Invincible Atlas opening up zones to put Deus-X-Krawler with Mind Meld while being beefy and hard to get rid of outside of non-targeting non destructive removal or battle in turn basically locking down the field while you go do your creepy Krawly things. Ballista can recycle whatever you banish for the Beetroopers when she dies and just get one heavy hit in with her debuff (making the Battlewasp an honorary Bee(trooper) *wink*)
Of course you can imagine the strategy is far from meta but as a huge Insect fan I just had to try to mesh them. If I used even more deck slots I probably also would've thrown in Battlewasps but they aren't valid materials for at least 2 of the Krawler link monsters so I decided against them for now (except for Big Ballista who's there to give the deck even more colour and possibly recycle stuff we used for the Troopers)
