Stun your opponent with Zexal, Handtraps and Floodgates and summon the mighty Rainbow Neos.
The best way to summon Rainbow Neos is through the Predaplant enginge (Scorpio to SS Cobra to search Neos Fusion). That way
before you activate Neos Fusion (since Neos Fusion locks you out of SS for the remainder of the turn) you can either link them into Beat Cop from the Underworld to give Neos extra protection, overlay them into The Phantom Knights of Break Sword to destroy an opponents card (only useful if going second) or overlay them into Number 3: Cicada King for disruption.
Obviously none of that compares to playing the Numeron engine Turn 1 and then crushing your opponent from there.
The Predaplant engine can also be used to search Instant Fusion to SS Thousand-Eyes Restrict to link all 3 into Selene, Queen of the Master Magicians. If there are 3 spells in the GYs or field you can then SS Thousand-Eyes Restrict from GY, link Restrict into Linkuriboh and link Selene and Linkuriboh into Accesscode Talker (or any other Link-4 that works). If you used the Numeron engine prior on your last turn you will have enough Spells for Selene's effect (Instant Fusion and Numeron Calling in GY and Numeron Network on field).
Since Neos doesn't provide much interaction with your opponent the handtraps and floodgates will come in handy since There Can Be Only One doesn't stop you from summoning Rainbow Neos (it does prevent you from summoning more than 1 Numeron Gate and from using the Predaplant engine so keep that in mind).
