So, I came up with the idea to make a fun, casual deck concentrating on insects mainly (this includes the Earthbound Immortal Uru). Now I really want to take it up to the next level but I need some advice on how to do so. Can you help me to edit this deck and make it slightly more consistent? Thanks.

Monsters
Earthbound Immortal Uru x1
Doom Dozer x1
Alpacaribou, Mystical Beast of the Forest x1
Insect Queen x2
Gigaplant x1
Insect Princess x2
Koa'ki Meiru Beetle x1
Cross-Sword Beetle x1
Beetron x1
Spyder Spider x1
Pinch Hopper x3
Prickle Fairy x2
Junk Synchron x3
Gokipon x2
Dark Bug x2

Spells
Heavy Storm x1
Multiplication of Ants x2
Dark Hole x1
Earthbound Revival x1
Pot of Avarice x1
Monster Reborn x1
Insect Immitation x2
Verdant Sanctuary x2
Supervise x1
Gaia Power x2

Traps
Spider Egg x2
Starlight Road x1
Dimensional Prison x1
DNA Surgery x2
Solemn Warning x1

Extra Deck
3x Stardust Dragon
1x Black rose Dragon
2x Underground Arachnid
1x Ally of Justice Catastor
2x Dark Diviner

I would definitely suggest some XYZ monsters for the Extra deck. Won't really help with overall consistency but XYZ's are always a great help when you're in a tough situation, and it's nice to always have them there. I don't know why x3 Stardust Dragon is necessary. What are the chances of you getting out 3 Stardust Dragons in one game?

Changes to extra deck:
-2 Stardust Dragon
+1x Vylon Disigma
+1x Number 39: Utopia
+2x Fairy King Alverd
+1x Number 50: Black Ship of Corn
+1x Steelswarm Roach
+1x Photon Papilloperative
+1x Daigusto Emeral
