Dragonite with Heal Bell
Heal bell is a normal move that could be associated with "cute" pokemon like manaphy, evee fam, most fairies, etc.
The only instance of heal bell Dragonite is from the game "Pokemon XD: Gale of Darkness" Shadow Pokemon event.
I'd argue this is not cannon and should not be part of the competitive landscape. I get that this does not make Dragonite OP and should be banned, but it is illogical and makes for annoying roost, heal bell set that can stall other mons in the tier.
Just my 2 cents
