The deck is built to counter meta decks/cards including Karate Man FTK deck, Wonder Balloon deck, 4-Starred Ladybug of Doom, and other meta decks. You can prevent Karate Man's attack from being conducted by using Sphere Kuriboh or Enemy Controller, destroy Wonder Balloon with Twister, and offset the effect of 4-Starred Ladybug of Doom by attacking with a high level monster.
Have Axe Raider, Judge Man or other high level monster on your side of the field.
Summon a Blue Dragon Summoner.
Activate Mythic Box to destroy a monster your opponent contorls. Send Blue Dragon Summoner to your opponent side of the field.
Attack the summoner with your high ATK monster.
The attack inflicts battle damage and the effect of the summoner gives you a non-effect monster from the deck.
By using Switcheroo, you will collect Blue Dragon Summoner or Gravekeeper's Recruiter and Enemy Controller. Send a high level monster or useless spell card (will be Twister if your opponent does not use a Wonder Balloon, an equip spell, or skills starting a duel with activated field spell) into the deck to get the other card.
How to get
[Switcheroo] Return 1 card in your hand to your Deck and draw another. The skill can only be used once per turn and twice per Duel.
Level reward: Keith Lv4
How to defeat the deck
Riryoku Field woks very well to defeat the deck since it can offset the activation of two key spells of the deck. Additionally, the Card Trader requires you to pay only Gold for the card.
Thank you for your comment. Blue Dragon Summoner cannot search Lord D since it is not a non-effect monster. However, I am sure the card will work well when you have BEWD deck to get the dragon from the deck.
