Wrath of Neos will return Elemental HERO Neos to your Deck and then destroy all cards on the field. Elemental HERO Neos being returned to the Deck is not an activation cost, so, if your opponent negates Wrath of Neos, you will still have your monster on the field. Use Sangan’s effect to add Neo Space Connector from your Deck to your hand.
Now that Wrath of Neos has completely wiped the field, you can activate Neos Fusion, send Elemental HERO Neos and any Level 4 or lower Effect Monster from your Deck to the Graveyard and Special Summon Elemental HERO Brave Neos from the Extra Deck.
If you have an Elemental HERO Neos and a Level 4 or lower Effect Monster in your hand and/or Graveyard, you can activate Miracle Contact before Neos Fusion to get around the latter’s restriction.
Elemental HERO Brave Neos gains 100 ATK for each “Neo-Spacian” and “HERO” monster in your Graveyard. If you have at least 1 Elemental HERO Neos in your Graveyard, Brave Neos will be able to get over Legendary Six Samurai - Shi En.
When Elemental HERO Brave Neos destroys an opponent's monster by battle, it allows you to add 1 Spell/Trap from your Deck to your hand that specifically lists the card “Elemental HERO Neos” in its text. You can use Elemental HERO Brave Neos’s effect to add Miracle Contact, Neos Fusion or Wrath of Neos to your hand.
If you already have Space Connector in your hand, you can search Wrath of Neos and, if anything happens to your Brave Neos, you can wipe the board.
Neos Knight cannot inflict battle damage to your opponent, but its ability to attack twice and the fact that you can Summon it both with Miracle Contact and Neos Fusion makes it extremely valuable in certain situations.
Beatdown will allow your Elemental HERO Brave Neos and Elemental HERO Neos Knight to get over high ATK monsters such as Legendary Six Samurai - Shi En and Ancient Gear Reactor Dragon.
Miracle Draw will make it easier to draw into your Wrath of Neos and Neo Space Connector.
Legendary Six Samurai - Shi En is able to negate Wrath of Neos, Neos Fusion and Miracle Contact; Six Style - Dual Wield and Legendary Six Samurai - Enishi’s effect can be chained to Wrath of Neos and return Neo Space Connector and/or Elemental HERO Neos to your hand, preventing you from returning the Level 7 monster to the Deck and destroying all cards on the field.
Even if your opponent activates Enemy Controller or Paleozoic Canadia in response to Wrath of Neos and takes control of or flips Elemental HERO Neos face-down, the monster will still be returned to the Deck and all cards on the field will be destroyed, but, if your opponent activates Paleozoic Canadia (or Floodgate Trap Hole) in response to Elemental HERO Neos being Summoned, you will not be able to do anything about it, unless you have Miracle Contact.
Although the deck has certainly improved under many aspects, it still struggles with consistency.
