Life Cost 0 You can use the skill when your Life Points are 1000 or less. You do not have to spend Life Points to activate a card until your opponent's next turn ends. You can only use the skill once per Duel.
Just like the usual Cyber-Stein decks, use its effect once you lowered your HP to 1000, and use your skill Life Cost 0 to special summon Blue-Eyes Ultimate Dragon or any other fusion monster from your extra deck. Although not as powerful as Blue-Eyes Ultimate Dragon in terms of stats, other fusion monsters in this deck have great effects that also make them worth summoning.
Arcana Knight Joker has amazing stats and can protect himself from any card effect as long as you can discard a card of the same type from your hand.
Blade Skater gains a lot of powerful effects depending on the number of monsters your opponent controls.
Use Cosmic Cyclone to remove from play any spell/trap card on the field. Use this during the turn you activate Life Cost 0 so you can activate it for free. Conversely you can use this to reduce your LP helping you activate Life Cost 0.
Activate Anti-Magic Arrows at the start of the battle phase to protect yourself from your opponent's backrow. Using this at the right time can help you to OTK your opponent.
Normal summon Destructotron to clear the spell/trap card zone of your opponent by lowering your own LP enough to activate Cyber-Stein's effect, you can also use Pyschokinesis to clear your opponent's monster.
Once you've successfully cleared your opponent's field for any potential threat to your combo, you can now activate your spell Double Summon and normal summon Cyber-Stein.
Can someone explain to me how D-D-D-Duel’s posted “KOG” can use Cyberstein’s effect when you only have 5000 lp to start and NO CARDS to increase your lp above 5000? You can’t spend 5000 lp when you only have 5000 lp.. maybe these “KOG” posts need to be looked over a little better? Just a thought lmfao
Where the is a triple abyssal designator?
And why not using thing like white elefant gift (works on fusion monsters) or maybe gift of the martyr?
Cyberstein could summon up to the limit of card in your extra deck when you activate life cost 0, so no matter if you sacrifice some of your monsters. Also, gift of the martyr help getting rid of cyberstein after using his effect, while abyssal designator is wayyyy to useful than destructotron (even if I use both of them).
Man this deck has an immense power, don't understimate it.
