As of now...
Who are your Top 5 Attacker which is available in your Dex? It means you always used when you attack a GYM.
In the present day...
Here's mine:
1. Gyarados
2. Exeggutor
3. Dragonite
4. Vaporeon
5. Arcanine
This doesn't mean that they are the best but in my case they are the available attacker that I usually used to defeat a GYM...
Edit: Since Blissey dominating as a GYM defender in our area, and that is why it makes my Gyarados as no. 1 Attacker

I use Dragonites for 80% of the attacking I do, if they're not sitting in a gym. The remaining 20% are usually Vensuaur, Exeggutor, Jolteon and Lapras. I prefer to prestige friendly gyms anyway, instead of tearing down other peoples work. My top 5 prestigers:
Jolteon TS/TB or Dis
Tangela VW/Solar
Cloyster FB/Blizz
Golduck WG/HP
Jynx Pound/PS (vs Snorlax)
My most-of-the-time squad (I'm at level 30),
- Dragonite (Dragon Breath - Dragon Claw)
- Vaporeon (Water Gun - Aqua Tail)
- Snorlax (Zen Headbutt - Hyper Beam)
- Tyranitar (Bite - Stone Edge) I felt emotional when I saw this moveset :')
- Gyarados (Bite - Hydro Pump)
I also use Jolteon (Volt Switch - Discharge) and Exeggutor (Confusion - Zen Headbutt) sometimes while Gyarados is around. Besides I have a decent Alakazam (Psycho Cut - Shadow Ball), but hey fella to be perfectly honest, Alakazam's defense and stamina stat sucks, I can only beat one gym defender with him (IV 91% and 2205 CP). Whereas using my aforementioned squad, I can defeat a level 10 gym with 1 or 2 of them remain alive.
Nevertheless, suggestions and/or questions are very welcome :)
•Dragonite
•Dragonite
•Vape (or Gyarados if feeling edgy. Sometimes I use Dragonite.)
•Eggs (or just Dragonite)
•Dragonite
•Espeon (in case i need something with high dps and don't feel like using Dragonite.)
I'm still trying to get a good one of those green wingless rock-dragonites (wtf am I supposed to do with iron tail/fire blast). Until then, I'll have to get by with Dragonite.
Is Gyarados that good against Blissey?
My list of attacker for Blissey by order of preference:
- Machamp
- Heracross
- Dragonite
- Tyranitar
- Ursaring
- Charizard
- Flareon
- Exeggcutor
- Gyarados (equal to Vaporeon)
Since you have an Exeggcutor and a Dragonite (and probably Flareon and Ursaring), I do not think that Gyarados is your best option.
