Mm... Wanted to do this earlier, but I didn't think I would battle so early :P. But anyway, here's my predictions for the first round:
DEZTROYA vs
Mr.Darkrai - Heard he plays UU and is good at it. Destroya isn't any slouch either, but I think Mr.Darkrai has the edge here
Macheep vs
Althos - Already won.
BlakBlastoise vs
Erodent - Hosted the last UU tourney so you know he knows his shit, and Blak doesn't play a whole lot of UU.
Jigo vs Harro237 - He's got the resources to put together a strong team.
Tri-DarkSouls vs Supe - I can't believe everyone's picking Supe for this match. TDS got really far in the last UU tourney, and has made the top 4 in both the Doubles and Mono-type tourneys, so he knows how to make good teams.
Diploman vs
Tase - RNG abuser FTW. :P
Deschain vs Magik0722 - Heard he got 2-0'ed by Canada and so I played Canada to see what his team was like and I snuck away with a 3-0 win, but for Deschain to even get close to winning that game, you know he's got to be good. Plus he's been practicing a lot recently (obvious from the Battle Me thread).
Fightgar vs
negator - Saw some of Negator's UU battles, and I feel really sorry for Fightgar... Getting Negato in the first round was just bad luck >.<
Honchkrow vs
Darkprophet - Don't know who Honchkrow is, and I'm pretty sure Darkphrophet has been here longer, so he's probably more experienced.
Slimi vs
wiinry - Guess.
krabs93 vs mikeeeey - Played him before at UU and he's pretty good.
Alakapimp vs
Geren - Guess, not sure how either of them are at UU, but I know Geren has a lot of my UU pokemon :P
TheForgottenSoul vs
asiankid123 - Guess. Wasn't TFS in the last UU tourney though?
Pablo vs Seafan - Already won.
Scruffy vs Eiganjo - Already won.
destroyer vs sandman - Another guess >.<
Can anyone link me to wiinry please? I want to set up a date with him but seriously I don't know who he is...
Anywho, I really suck at battling, and I only battled once on smogon against foibles who beat me either 4-0 or 3-0.
