Hey bud would ya mind checking in on my league to see if thy know I'm out of commission for a bit? I was told it was a Torn ACL but patently its a snapped tibia (broken keg pretty much). How the doc confused an AFL with a snapped leg irk but I'd like to know I my guys knew
Also definitely use trace.
As for the moves, Moonblast + Focus Blast are mandatory. I prefer Psychic > Psyshock, since without Taunt (you're using a scarf) you'll never beat Chansey anyway, and Psychic is overall much stronger. The last move is your choice between Trick and Healing Wish. I prefer Healing Wish, since it lets you revive any sweeper on your team, but Trick is also acceptable for crippling chansey. Chansey's popularity is decreasing, though, which makes me prefer Healing Wish even more.
