-Protect
-Wish
-Toxic
and one of the following moves.
Scald is pretty self explanatory, though it doesn't do all that much damage.
Mirror coat is pretty good on it thanks to massive HP, KOing most stuff when it's not expected, and even when they know you have it, it lets you play mindgames and give wishes to teammates.
Soak is also pretty decent if you want to remove STAB and toxic just about everything, but it does make you taunt bait.
Waterfall does some respectable damage.
Knock off is not a great option, but you can consider it.
U-turn is ok for wishing teammates.
