I used Ho-Oh today at a League Challenge (and so did 1 of my friends), and I placed 3rd and he placed 2nd, me going 3-2, but one of my opponents scooped to me, so my record was 4-1. The game my opponent scooped was really close (I flipped a lot of heads, and he drew badly, but I started Ho-Oh, and my other Ho-Oh was my last prize, so it sorta evens out), and the other I misplayed (might've still lost anyway). The Lasers were okay, I can't really judge Virizion because I didn't face much with Lasers, and my 2 Bouffalant didn't do anything. I also played a Landorus EX, and that was really helpful.
I faced:
Vir/Gen loss (misplay)
Emboar.dec win
Some... thing (all I saw was Meowth) win
Vir/Gen win
Garchomp/Landorus/Dusknoir win (he scooped)
Make of this what you will.
