Levitate Chandelure - Hm... Not sure what to say about it. It still has four other rather common weaknesses to deal with, and one of those is Rock (which means SR and the other part of EdgeQuake). MegaSaur having Thick Fat doesn't help matters, either.
Roost non-Mega Heracross - Regular Heracross is an offensive Pokemon. Roost is useless on Choice sets and pressed for a moveslot on other ones, and it gets rekt by Bird teams regardless of healing.
Poison Heal Snorlax - An idea I've thought of myself, actually. It does seem really monstrous, and we should get some calcs to see what can still get past it (I don't have time right now to do it).
Drizzle Bronzong - Intriguing, definitely. It's essentially Heatproof and more, and gives Rain a needed setter. However, MegaYard still doesn't give a shit about it, and Bronzong's big issues this Gen are its two new weaknesses and an even higher power creep.
So, in conclusion, going to vote for Poison Heal Snorlax.
