The thing is he sometimes brainlessly sends his airman/blazeman in front of your Paladin. If he does so early in the duel, he can mill up to 8 cards and that can be a problem if you can't draw your key combo cards in time.
Remove this Fiend Megacyber. Add any other, like Dark another buster blader. Outside game add one Elemental Hero Neos Knight. He came with 3800 atk and Bister Blader on opening hand is higher than Megacyber.
Fiend megacyber is just an insurance, lol I'm not even using it on the final turn. But there's that rare moment when my paladin was destroyed early because I let a poly slip on Jaden's field, so I'm left with RESD and lacking a 2nd monster for vassal. Then that card saved the day. :p
Just destroy the blazemen/airmen or whatever they are turn after turn. You can keep him from decking out first because:
1) Pot of Benevolence (returns 2 cards)
2) Fusion Trap (mills from deck)
3) That spell which can mill a BB from deck
4) Field spell (can mill a Poly)
5) King of Swamps (can mill a Poly or two)
