My two cents on the meta currently.
I have been playing pretty much constantly on the ladder, and I have yet to be screwed by ohko moves. That said, I don't believe I've faced someone setting out to abuse them, so I'll of course keep testing.
I've been running a Resttalk Kyogre on my stall team with scald/sheer cold, and it has been highly underwhelming. I think I've killed like 2 things in 25+ games in the last two days. Almost in all situations I'd rather have toxic or ice beam or even thunder wave.
However, while writing this post, I was just haxed to HELL by this guy testing a 3 mon team of Groudon/Kyogre/Mewtwo. Groudon and Kyogre killed 5/6 of my guys with their respective OHKO moves. This makes me wonder. However, I feel that I was just unlucky. Thankfully the player was nice and quit, saying he was just in it for the testing. HE should get to vote, whoever he is.
EDIT: Ha! He just posted right before me.
If you would like help on any aspect of team building, would like me to rate a team, or have a non postable team you would like me to take a look at, I am just one pm away.
