Okay, I've got a few things to say, although I honestly don't think I need to defend my decision.
You have 0 posts in the Doubles OU forum before your vote, so I can assume that you would not have voted here at all if Caasi hadn't asked you to vote in the competition. Even if he didn't explicitly ask you to vote for him, it was asking you to go vote that got him an extra vote. I also received proof that he asked another user to vote for him. The rules were not made explicitly clear in the OP, so I had nothing specific to fall back on. As a result, I decided to just ignore the fact that many of the votes were a bit fishy and take the numbers at face value, 5 for shaian, 5 for Caasi.
After looking at both teams, I honestly believe shaian's to be more widely effective and a better showcase of Kartana in the current metagame. Choice Scarf Kartana is a niche set already, and if even I were to use it, Night Slash not be my first choice of a move on Kartana, as it only really helps against Aegislash, Metagross, and Bronzong. shaian's Bloom Doom set, paired with Pokemon that appreciate the removal of bulky Waters like Volcanion, showcased Kartana at its most effective.
It's always been up to the host of the project to break ties, and you're allowed to disagree with my personal call, but in the future please refrain from attacking the tier/the staff team/the project. Doubles has one of the largest playerbases it's had in a while, so going from "I call everyone in the doubles ou room my friend" to "no wonder this tier is dying" doesn't really follow for me.
At the end of the day, there's very little physical reward for winning a round of this project. Caasi got to showcase his team and have 5 people give him the recognition that they believed he should win this round, so all that he's missing is the moving of his team to the Hall of Fame. I'm sorry if you feel that I've in some way personally wronged you, and I hope that this explanation at least clears some things up. Enjoy the hiatus.
