Bullet Seed/Solar Beam Exeggutor.

BS has the seventh highest EPS value, so yeah... even with the low DPS, you can charge SoB really fast and hit vaporeons so hard it's not even funny.

not the best overall attacking set, but it will destroy watermons

I prefer Confusion/Solar Beam because confusion Chews through health like nobodies business. 6-7 confusion hits with 1 SB ends 2300 and below vaporeon/Rhydons. BS/SB takes more time to kill them.

I have one and really like it. Have not powered up yet because I'm wondering if Extrasensory/SoB would be better. But it is definitely a very useful moveset.

You have yourself a very awesome Rydon/Vaporeon killer there.

I managed to get that move set on one and BS charged SolarB so fast I managed to use 2 SolarB on a Vaperon and killed it before it could use HP and had the bar charged to hit the Rydon that came in after with a SolarB on first move.

The trainer is basically spamming SolarBeam every 5 seconds with this setup :).
So beautiful.
