Elite attackers

P/HB Blissey, still likely to time out against Blissey.

C/SoB Egg makes it into nearly every attack line up.
It will do well against Rhydon, Vapes and even Blissey and Snorlax.
Quite often, there is multiple Eggs in my line up.

Once it enters the fight it very rarely gets swapped out.

In my opinion, Poliwrath is very useful, I prefer Bubble over Rock Smash, and it charges Dynamic Punch in less than 6 seconds.

My Exeggutors aren't strong enough, 3 of them got Zen Headbutt, and the other one got Extrasensory/SeB.

Given the more common presence of Blissey as a defender, you DO want to power up your attacking Blissey if you want to do a clean sweep of your bottom 6.

If there are 4-5 Blissey at the bottom of the gym you are probably going expend 1 attacker per blissey (exeggutor, dragonite, whatever). Maybe maximum 1.2 Blissey per attacker.

Once you clear of the 4-5 blissey you will most likely only have 1-2 mon left. You would definitely want one of your remaining attacker to be Blissey, as she is the only pokemon that can steamroll the remainder non-blissey pokemon (snorlax is the only comparable one and it's not even that close)

I don't have the luxury of a P/HB blissey but I use my L/HB Snorlax as a reasonable substitute. Usually goes through 2.5 to 3 top class mons with dodging, but Blissey may well do 3.5-5.

I trhibk that scizor is really underrated. While he's average in bulk, his attack stat is really strong. He is also only weak to one type: fire (the type that nobody puts in gyms because vaporeon crushes it)

I finally rolled a high level bite/stone edge tyranitar and he's great. one of my elite attackers. bite is superb for dodging and tyranitar's bulk last longer than dragonite. the best attacker vs blissey imo.

regarding an attacker p/hb blissey; yes you win your matchup, but it takes forever and it's crap vs other blisseys. Since the pareto comparison came out My current elite attacker is my dragon breath / dragon claw dragonite. I'm a dodger and dragon breath is great and dnite will last a long time with dodges because I can dodge all specials and most dragon tails with dragon breath and still finish with plenty of time

P/HB Blissey is definetely your number one choice if you value potion and revives a lot. I guess this also depends on how many Pokestops there are available in your area.

I'm more or less forced to use Blissey as my main attacker (and it's doing excellent work) but if I had more Pokestop available I would probably choose differently, because I value time a lot and it's not the fastest choice.

That being said, having a level 31 P/HB Blissey available is always a good back up. Try it out and you will see how efficient it is. I once managed to kill 5 Pokemom with it.

I'm a little late to the party, but I constantly find myself using Muk. He is bulky and does really good damage. I find him a solid option against Blissey. Other than him, the only out of the ordinary pokemon I use in most battles is Tangela.

HP Vape as finisher if needed in every case and for taking down 1 or 2 other mons (with dodge everithing took also a Dragonite after dealing with a Rhydon). I don't have a l/hb snorlax or p/hb blissey and my p/dg blissey is also in a gym usually; vs. Dragonites worked well but I preffer Lapras anytime.

Machamp with C/DP.
If you only dodge specials he is faster, if you dodge all he is faster AND has a better kill ratio than Bite/SE Tyranitar.

Defeating a lvl 10 gym full of Blissey's is a pain in the ass, but I've managed to take it down, since most of my attackers are maxed out to lvl 39. Here's a chart that'll help you.
