Ah, Alomomola, why do you go unloved?
To be honest, I always saw this thing as a supporter, and I think that is what it's built for. Heal Pulse, Wide Guard, Helping Hand, Wish, Safeguard, Healing Wish, it has everything save for Heal Bell. I also think it could be proficient in doubles. What this thing really needs in order to hit top tier (at least in doubles) is telepathy.

This fellow can keep things like Heatran or Terrakion going for a long time, Blocking Blizzards and Earthquakes while buffing Rock Slides and Heat Waves. Heal Pulse and Healer keep your sweeper safe while he tears everything up, and Scald is a backup offensive manuver.
