This metagame seems pretty unexplored. I expect stall will probably be a generally effective strategy against all but the most offensive of teams. I'm not sure what I think of Kingdra. It kinda made the game a stalemate for a long time when I faced it in the tournament; I was forced to stall it back for a long time then took a couple of risks and I think it eventually died to a crit? Maybe I am remembering wrong.
It would be good if we had some more games to go off to test all this stuff. How many games have you all actually played recently? Are you practising on the PO server? I have played six games and lost one (to Crystal_ who totally obliterated me), so I don't really have a lot of experience yet...
