You can also use "Chimeratech Rampage Dragon", since its Summoning Conditions are less strict than the other Chimeratechs. Plus, with "Megamorph" and its effect, that monster will be able to inflict 12,600 ATK at best.
After using this card's effect, equip it with "Moon Mirror Shield" so that it will overpower the Monster that battles it. This goes hand in hand with "Clashing Souls", which will also allow you to perform the above OTK, with or without "Megamorph".
Special Summon this card with "Last Will" after using the effect of "Chaos Emperor Dragon - Envoy of the End". Use this card's effect to summon a high-ATK Fusion Monster, and attack directly with it for an OTK(Note that while you can also use "Black Rose Dragon" as the Nuke, "Chaos Emperor Dragon" also sends all cards in the hands to the Graveyard, and inflicts 300 damage for each card it dumps).
"Naturia Exterio" is a fairly powerful monster that can be Summoned with this effect, and grants yourself protection from your opponent's harmful Spell and Trap Cards like the aforementioned "Magic Cylinder". In addition, it is fantastic for protecting cards like "Brain Research Lab" or "DNA Surgery" if the method mentioned above is used to circumvent the cost of the effect.
Use this card's effect to summon "Odd-Eyes Vortex Dragon", returning one of your opponent's Attack Position Monsters to their hand.
"The Last Warrior from Another Planet" is a very powerful Fusion Monster, and it can be Summoned with the effect of "Cyber-Stein" to prevents your opponent from Normal, Flip, or Special Summoning any monsters. Play "Light of Intervention" to create a Summoning lockdown with "Last Warrior".
Afterwards, you can select "Last Warrior" via "Last Turn", preventing your opponent from Special Summoning a Monster through its effect.
Use this card in Machine-Type Deck such as "Geargia" or "Karakuri" to OTK your opponent as both or these Deck can Xyz Summon "Gear Gigant X" very quickly to search for this card. Special Summon "Naturia Exterio" as to counter opponent's Spell Card or Trap Card.
To avoid using up your Normal Summon, Special Summon this card with "Magnet Circle LV2". This way, you can then Tribute this card for another monster to save yourself Life Point damage if your opponent can't be defeated that turn.
This card itself is very weak. Try to protect it with Traps, or make it stronger with Spell Cards, because if your LP are very low after using its effect and your opponent survives, they might finish this Duel by destroying this card. "Cyber-Stein" could also be Tributed for the effect of "Crush Card Virus" after using its effect, so there won't be any vulnerable should your opponent survive your attack.
