I have a new strategy for my machines. It's very similar to my "Chimeratech assimilation" combo. Now, rather than having to draw Cyber Dragon, DNA Surgery, and Super Polymerization, I just need to draw Cyber Dragon and DNA, and I can keep the monsters on my side of the field and my spells and traps if I wish. Why?
Chimeratech Fortress Dragon. It's like the Overdragon, but it has a super polymerization ability built into it, it gains 1000 per monster rather than 800, and it doesn't destroy all my cards when it's summoned. Even better: Once it dies, since the monsters were sent to the graveyard, I can still use Overload Fusion to bring out the Overdragon.
