Cyber-Stein OTK

This OTK involves three cards, Cyber-Stein, any Fusion Monster with at least 4000 ATK points (the most common being Master of Oz and Blue-Eyes Ultimate Dragon), and Megamorph. First, Summon Cyber-Stein and activate its effect, paying 5000 Life Points to summon the Fusion Monster. Then activate Megamorph and equip it to the Fusion Monster. Since your Life Points will most likely be lower than your opponent's after the 5000 Life Point cost, Megamorph will double the Fusion Monster's ATK points, raising it to at least 8000, more than enough to wipe out your opponent. Skilled players will also add in Spell/Trap and Monster Removal to ensure this combo will succeed.
