1. Tsubame Gaeshi (love to return shots in that fashion, would piss people off if done in real life)
2. Higuma Otoshi (same as above yet love to return smashes and indirectly showing the opponent that their smash is weak)
3. Fu Rin Ka In Zan Rai (love the concept, yet I would make a few tweaks in the manga)
4. Synchro (just because I love doubles)
5. Kikumaru Beam/Bazooka (awesome)
As for concepts, my favorite use to be Fuji's counters but with all these new techniques being introduced, I think Sanada's Fu Rin Ka In Zan Rai and his awesome aura made him my favorite. My top five also include Marui's volleys, Kikumaru's acrobatics, and Oshitari's "man of 1000 techniques," yet to be seen.
p.s. give cyclone smash a break already lol and everyone's copycat moves
but I'm pretty much in the same boat as all yall, it gets a bit repetitive
