Nominating Dragonite for A rank. The original dragon is now a reborn threat in this meta due to the lack of competition for a team slot he has in the standard OU meta with things like Mega Altaria and Charizard X. He's one of the two better Dragon Dancers in the meta(the other one is Gyarados) thanks to Multiscale that basically guarantees at least one DD up and also Extremespeed that allows it to not be easily dispatched by Talonflame and Ice Sharders such as Weavile and Mamoswine. Also if one prefers immediate power it can run a great Choice Band set as well with good power and coverage and +2 priority to boot. The only thing that keeps it from A+ rank imo is that hazard removal support is mandatory and this can be harder to accomplish comparing to standard OU, mainly because of the dominance of Bisharp that threatens Defog users, as well as Starmie.
