I'll do Vrai-style predictions cuz why not.
FLCL v Annoyer
Annoyer will john, but like a ruthless hunter, king FLCL will track him down and force Annoyer to battle. FLCL will win 2-1. First time Annoyer will be prepared for FLCL's Liepard antics and will make use of the strong Cradily (and an added extra of no SR becuz who needs SR in NU??? it's not like Zard is good or anything) In the next round FLCL will come back strong, using a standard Liepard offense team while Annoyer prepared for another of FLCL's gimmicks, and ends up taunting Dark Gem Nasty Plot Unburden Liepard - something of which he has a huge weakness to. Unfortunately for Annoyer, round three is where FLCL brings out a hax team (as in literally each game ends with a crit) and ultimately will come closer to winning yet another tournament.
Shuckleking87 v Tachycardia
Shuckleking may have won a tournament before (and Tachycardia might've too) but this is not his time. Shuckleking will be cool and use Shuckle, but Tachycardia will bring out something even stronger than Shuckle: Delcatty! I don't know what it'll do (or can do) but it'll do something to scare out the weak turtle and give Shuckleking the loss in the first round. In the second round Tachycardia has a minor heart attack and during it accidentally sends out Shedinja as a lead versus Golem, oops! Luckily for Tachycardia it's CB Golem with Explosion, something all the cool kids use. It explodes and Shedinjda does nothing, giving Tachycadia a lead of 6-5. After that, though... Shuckleking realises Tachycardia's gimmick and sweeps with Bulk Up Substitute Sawk, because hey that's how Sawk's meant to be used, right? In the last round Tachycardia comes out on top or should I say comes out on trop with a classic sunstall team featuring Tropius.
Zebraiken v Sweet Jesus
Vrai will be prepared for SJ's creative movesets and bring in even more creative movesets. Expect to see a Zweilous sweep here people! This in particular will be funny cuz he'll be pissed when it misses half way through its sweep :'( However he will come back in the second round with something even more creative: Swadloon, as hearing about Enguarde's battles had inspired him in a way. SJ will not know what's coming and will lose second round. Third round will be won by Vrai as SJ relies on Specs Tauros to catch Vrai out. Unfortunately for SJ, he catches on and sends out his Kecleon, forcing SJ's Tauros to switch and then lose to CB Kecleon.
