Waited for other people at a level 4 raid. None showed up. Found a level 3 raid instead against a Vaporeon. None showed up, so I decided to take it on. Not too confident after failing against an Alakazam yesterday, but I figured that Vaporeon was easier and that I had better counters to Vap than to Ala.
The Vaporeon has Water Pulse, which ought to be the easiest moveset to beat.
Team 1:
3063cp DT/Hu Dragonite
2632cp BS/SoB Exeggutor
2345cp ES/SoB Exeggutor
2265cp BS/SoB Exeggutor
1920cp ES/SoB Exeggutor
2326cp TS/TB Jolteon
This attempt failed timed out, but I was quite close. I thought about powering up a L20 Venusaur, but really wasn't feeling like spending the dust. Instead I evolved a L28 Exeggcute and got another ES/SoB Exeggutor. For the second team I also added another Jolteon and dropped the Dragonite.
Team 2:
2326cp TS/TB Jolteon
2275cp VS/TB Jolteon
2632cp BS/SoB Exeggutor
2345cp ES/SoB Exeggutor
2265cp BS/SoB Exeggutor
2197cp ES/SoB Exeggutor
To me, that looked like enough firepower, but it wasn't. Timed out again. I didn't want to power any of those Exeggutors up - not good enough IV's, but I vowed to not dodge at all - unless it would enable me to get another charge move in and I put back the Dragonite instead of the weakest Exeggutor.
Team 3:
2326cp TS/TB Jolteon
2275cp VS/TB Jolteon
3063cp DT/Hu Dragonite
2632cp BS/SoB Exeggutor
2345cp ES/SoB Exeggutor
2265cp BS/SoB Exeggutor
The phone rang in the middle of the battle, but I hung up and continued and JUST made it with 0-1 seconds left (and i was. I don't think I attempted a single dodge. Just attack spamming. The Dragonite did good work. Definitely an improvement over the L28 Exeggutor that was ditched. The sixth member never came into play though, so 5 strong counters should be enough.
But this team was JUST enough and might take more than one attempt to win. I'm not sure it would make it against an Aqua Tail or Hydro Pump Vaporeon.
