So not only is your Red-Eyes deck so much worse than the one I showed you. But you have the audacity to run Superheavy Samurai like that. But first, regarding Superheavy Samurai
If you're going to be playing Battle Ball, RUN KAIJUS. You can bring out your big synchros off a normal summon because of that you also run 3 of them. No if's and's or but's.
Blue Brawler, is GARBAGE. Why would you run a card that can't facilitate a play?
Also if you're running Giga Gloves, you combine it with Mathematician or Scrap Recycler and make a build built around that. Otherwise you don't run it.
Samurai Helper is so bad, Soul Buster Gauntlet DOES A BETTER JOB.
Soul Claw, you CANNOT justify this card. Your monster's will typically NEVER be run over by battle, they have high defense. In some situations they can, but goes back to my main point, they're more vulnerable to card effects.
Peacemaker, this card is stupidly good. If you have for say Soul Piercer in hand with this card and your opponent has no backrow but you have a level 2 tuner, you can normal summon Soul piercer, use Peacemaker on it, tribute it to play a Superheavy with a more optimal level, which can also be your higher levels. You'll also be able to add a Superheavy Samurai card from your deck to your hand.
Transporter, I personally can't stand this card, giving your opponent monsters or cards in general are really bad.
Also why aren't you running 3 Flutist? It legit helps bring out your higher levels and makes Musashi Plays really good.
Wagon: Am I a joke to you?
Soulbuster Gauntlet is your main OTK card, why aren't you main decking it?
Soulshield makes your monsters gain a TON of defense, 1200 defense gain is nothing to scoff at. Anything that pushes the OTK is needed.
Backrow can be VERY dangerous, so why not run Thief in the main deck and steal their card? You can steal people's potential backrow that can make or break the game. I remember stealing a person's Solemn Judgment because they didn't read Thief.
Sekka's Light adds a lot of consistency even though we can only run 1 currently. It can fix up hands, let's you draw.
For the extra Deck, your 2 best synchros you should run them at 3. Ogre Shutendoji, and Musashi.Stealth Ninja and Ninja Sarutobi are at most a 2 of. You also would want 1 Kyubi for big beater.
