Since not much people use insects, I thought I'd make an insect deck.
Monsters:
Insect Knight X3
Aztekipede, the Worm Warrior X3
Bee List Soldier X3
Cross-Sword Beetle X3
Doom Dozer X2
Howling Insect X3
Magical Merchant X3
Mother Spider X2
Spyder Spider X3
Spells:
Enemy Controller X3
Heavy Storm
Lightning Vortex
Mystical Space Typhoon
Pot of Avarice X2
Solidarity X2
Traps:
Call of the Haunted
No Entry!! X3
Torrential Tribute
As you can see, this deck focuses on getting the opponent's monster into Defense mode, good for Mother Spider. It also has some decent draw power, thanks to Bee List Soldier, and Magical Merchant is there to dump some insects down for Doom Dozer and Aztekipede, the Worm Warrior, what do you think?
