Chernobog is a godly rank 7, you should try it.
You can try using Arachne to tutor Megalo straight from your deck, and use the discarded card for megalo's effect. You can also run Heavy Armored stagbeetle in the extra, you can xyz into it by using a lv4 mosquito and something, then summon Mosquito and it got refreshed and ready to reuse its effect. Bug hive, Vermin engine, the field engine all are cloggy, you should cut them for more traps(or a way to get around them).

you could also stand to play silverwing moth and giant mutant rat

Ash, do you think Compact Earth + Megalo is a bit silly?
