So:
Superheavy Samurai Prodigy Wakaushi Girsu, the Orcust Mekk-Knight and Speedroid Terrortop are your main Starter. You propably know the line with Girsu and Speedroid so i will only explain SuperHeavy Samurai.
Place Superheavy Samurai Prodigy Wakaushi in your right Pendelum Zone. Activate his effect to place Superheavy Samurai Monk Big Benkei and to special himself to the field. Activate Big benkei effect to search Superheavy Samurai Soulgaia Booster . Activate his effect to attach it to Wakaushi. And activate his second effect to special him on the field. Now you have 2 machine monster to go into R.B. VALCan Booster .
If you get Ashed on Big benkei effect you could activate Wakaushi monster effect. But it locks you into superheavy samurai, so this is really your last option. If that happens: Special Superheavy Samurai Big Benkei and synchro both to get into Superheavy Samurai Brave Masurawo . Good tower with 4000 def and can attack in def mode. Also you can activate Wakaushi effect to place him in the pendelum zone again. NOW TRY TO PLAY EVERYTHING YOU HAVE. Thats very important. Because Masurawo lets you up to 3 Cards if the opponent activates a spell or trap. So you have the chance to draw some outs.
Also Superheavy Samurai Monk Big Benkei Has another effect. He can special himself if you mill Superheavy Samurai Big Benkei from deck or hand to gy. So he is not as big of a brick.
Also since there is now Sky Striker Ace - Camellia you can use for example monk big benkei, with any handtrap and go camellia than activate effect to mill hornet drones. Than Sky Striker Ace - Kagari to add back. Activate Hornet drones. And you know the rest of it.
Ye. Have fun. I think its my fav way to play R.B.
