Notes & Combos
Had to make a couple of budget choices here, which is why you only see two hand traps (Veiler and Imperm), as well as Pair Cycroid and Wind Pegasus, so swap stuff out as needed, but make sure you keep the two Links and your necessary combo pieces, as well as the CyDra Fusions.
Standard Cyberdark plays, but this event made hand traps much less scarier, so you're more likely to pull off a Turn 1 Cyberdark End Dragon than in Ranked. Step 1 is to get 3 Cyberdarks and Cyber End Dragon (Horizon does this one) in the GY, Chimera and 1 other Machine-Type on your field, and to have a Spell/Trap in your hand. Use Chimera's effect to fetch Power Bond (hope you won't need that S/T you held on to!), then Link Summon either Seiger or Knuckle. Chimera dumps your last Cyberdark into the GY, and lets you banish from your GY if you Fusion Summon. Play Power Bond and summon Cyberdarkness, equip it with Cyber End Dragon, then Tribute it for Cyberdark End Dragon.
Depending on your hand, the combo can vary wildly, but it works out best if you can also get Cyberdark Invasion on the field. Generally you'll want to use Cyberdak End and Invasion to recycle Herz, because sending it back to the GY will let you either fetch Cyber Dragon from your deck or GY, or recycle Core from your GY, which keeps your Spell/Trap searches going.
If you can get Cyberdark Claw equipped to Cyberdark End, that will help you dump Wind Pegasus and Skull Wagon, both of which have GY effects that can help you in a pinch.
While it will almost never happen, it IS possible to summon that second Cyberdark End Dragon. You need to use Anger Knuckle to revive Cyberdarkness, but since it's effects will be negate you'll have to use Cyberdark Invasion to equip it with Cyber End Dragon from the GY. After that, just Tribute away!
Best advice I can give you is to try to be flexible in your thinking. While your MAIN goal is Cyberdark End Dragon, don't lose hope if that path becomes blocked! There may well be other avenues you can use to gather the materials for victory. And definitely don't forget this: Even if you're sure Cybernetic Horizon will be negated, playing it anyway can still help since you still have to pay its cost, which will put Herz in the GY.
