I like it, however, the lack of swarming and backrow control makes me think these decks aren't competitive enough in the higher ranks? The only card that can have a decent match up is silent magician lvl 8. If they can find a way around that, it's over. It's not that the insects are hard to beat. I might be wrong here, as I don't run a lvl deck. Think with me?
The insect can be destroyed by a variety of ways but once SM Lv8 comes on the field, only traps will be useful. Then the focus shifts from the insect to the Magician. 1 mirror wall and 1 anubis can be replaced by 2 Seven tools/trap jammers
Although I don't think this deck is KoG worthy. Atleast I didn't reach KoG with this. Balance Anti-meta statue and 3SD Toon Barrel dragon + Toon kingdom helped me reach KoG
The problem as a PvP deck is that it doesn't pack the punch that a straight-up Silent Magician deck carries. Silent Magician is easier to get in play, more powerful, and isn't hurt by using Level Up! as a summoning strategy. Ultimate Insect isn't really viable in PvP if you want to compete. If you want to have fun though, that's a different story.
