Side deck is just thoughts. ED could be refined
Face Cards:
Insect Queen
Ultra Cocoon
Paranoid Parasite is the best Cocoon enabler
Killer Needle is a summon from Gokipole
Multiplication of Ants is ok for links
Bio-Bug (Bio Insect Armor) is a Cocoon target, and makes tiny bugs a threat
Gokipole is removal, but also card advantage. It can get Resonance insect
Resonance Insect is not a once per turn, and is always gas.
Retaliating C punishes spell summons and good Pico equip
Doom Dozer is strong and searchable from Resonance, and an extender
Antlion is an extender and removal and a Cocoon target
Faeri is an extender, Can make Baronne
DragonByte can be 2 bodies, but can make the Arachnid Synchro which is a cocoon target
Spine is removal and is level 2 for Arachnid Synchro
Foolish is for GokiPole or DragonBite
Called By is Called By
The rest are hand traps and breakers
ED:
Underground Arachnid is another Cocoon target but also good removal. And it seems kind of Weevil-y to me
Cicada King is a negate
Almirage is mostly a starter for getting Resonance Insect or Gokipole into the GY
LinkSpider allows Ant Tokens or Killer Needle to be more useful (Different name, becomes an effect monster etc for link climbing)
Armor Horn lets you normal a second time to combo off
Picofalena makes a Cocoon target, but also lets you recycle 3 bugs to draw and also lets you equip Resonance/BioBug/Parasite/Retaliating for extra value
Seraphim Pap is just an amazing card
Invincible Atlas is a boss and lets you do something with the Ant tokens
