I`m a bit worried about Rage in that deck. Confidence +6 Damage is nice, but you only have damage for KO, and you have to win the previous round.
Often goos decks in Tourney aim to win as many rounds, while a KO is nice if your opponent somehow manages to predict you, it easily lets them have more points over you and lets them win more rounds. An ideal Tourney situation in my opinion is you winning 3 rounds and winning the overall fight.
Another thing is to check your opponents playing styles. An advantage to Tourney is that having a fair mix and chances to give the same opponent gives you a chance to learn their play-style in Tourney to adjust accordingly.
