Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by banishing 2 Insect-Type monsters from your Graveyard, and cannot be Special Summoned by other ways. When this card inflicts Battle Damage to your opponent: Send the top card of their Deck to the Graveyard.
The Ultimate Insect monsters can evolve from lower levels to special summon their higher levels. This sends the lower levels to the graveyard so you can later use for Doom Dozer. But you can always just use the a regular card searcher like Gokipon to help with card draws and use other ways to send them to the graveyard.
These cards can help send cards from your deck to the graveyard much faster, but they can potentially send Doom Dozer to the grave as well. If you have 3 copies of Doom Dozer, running these cards can make it much easier to summon it early in the game.
Resonance Insect is one of the best Card to use this card’s effect because Resonance Insect can search this card from your deck, and when Resonance Insect is Banished, you can send 1 Insect-type monster from your deck to your Graveyard, giving you a chance to Special Summon another Doom Dozer from your hand to your field.
Another good card to use is Pinch Hopper and Bee List Soldier which can speed up your process to send your Insect-type monster from your deck to your graveyard for Special Summoning this card from your Hand.
I think Mefist tIG is better than this if isn't nomi. Though his ATK not really high but has ability to discard 1 card after gives battle damage is more useful in PvP/ PvE. Additionally, gives piercing damage
