Well I calculate who will win based on everything on the player card you have done once you have won 10 duels you win round one. SO LETS BEGIN ! Okay so the fight starts with .... Ranger doing Ataru and PWN starting with makashi then I try to get him with Ataru but his Makashi keeps me at bay just about I switch to Soresu to counter Makashi due to Ataru not working right now then due to Soresu being me primary skill Makashi cannot break it so you switch to shii-cho to try and break the defence and cause me to go back to Ataru Soresu can match Shii cho blade to blade and then I attack with the full force of Ataru and start hammering at you're defences so you switch back to Makashi but Masahi although it is good cannot stand Ataru in its full force and I break though you're defences due to the fact under strain against forms like for 5 and 4 can power though defences but thenn as Shii cho is deployed you match my Ataru barely with due to Shii chos random element and hold my attack back so I am forced to go back to my Soresu form to hold you off but due to its lack of needing energy I hold you're wild attack off easily then engage with the last bit of Energy with Ataru and manage to defeat you just barley.
So with that I win the duel though I must say it was only a slight edge the mainfailing of you're card was you had nothing to really power though my defences when I was recharging my energy so maybe you may consider changing you're card to form 5 or form 6 this was a good first duel and good luck in future vitamin PWN !
EDIT
Another reason was that Makashi to power though opponents defences requires strength lots of strength I may add.
