Looking back, which legacy moveset do you wish you had?

A Confusion/SoB Exeggutor.

This is an easy one. There are 3, C/SoB Eggy, ZH/BS Snorlax, and RT/RS Omastar because I think he is awesome.

RT/RS Omastar is the only one I kind of regret.

The only ones I specifically wish I had gotten are Confusion/DazzleGleam Alakazam (like you), Confusion/Seed Bomb Exeggutor (I got some with Confusion and some with Seed Bomb but not both), and Rock Throw Omastar (I didn't have enough candy back then). Those seem to have been the most useful of possible sets.

At least I have a ZH/Body Slam Snorlax...

ZH/BS Snorlax WITH great IV, high attack, high CP gain.
I have 3 and the best ivs is:
9 7 15 hp at df level 8
the highest level is:
2584 cp at level 30 (found like this in wild).
RT Omastar is far second.

Guys why Confusion/DazzGleam Alakazam is so good?

I wish I had ZH/BS Snorlax, RT/RS Omastar, DB/DC Nite

I do have...
C/DG, Pc/DG Alakazam
IS/IB Lapras
C/SoB Egg
C/SeB Egg
and legacy Gengars to name a few.

A tie between

1.Snorlax ZH/BS

2.Omastar RT/RS

3.Lapras IS/IB

DB/DC Dragonite, of course
Mud Shot/Earthquake Golem

Although there are less needs for ground type attackers now, Golem was my first big evolution that I got enough candy for and I was really disappointed in Rock Throw/Earthquake.

I am seemingly luckier than you guys here as I got the high IV mons with those desired legacy move set. For me I wish I could have a Dragon Breath Gyarados (don't even have enough candies to evolve one when the move was ditched), and an Ice Shard+Any Ice move Lapras(My very first Lapras was caught a few days before Gen 2 launch, and it's got Frost Breath)

I'd love a ZH / BS Snorlax but I don't even have one yet. I do have a IC / BZ Lapras, DB Gary, C / PC Eggy which are quite useful.

Con/Sob Exeguttor, DB/DC Dragonite, ZH/BS Snorlax,

I actually transferred 2 C/DG Alakazams at the time I evolved them (before the CP shakeup so he was around 900 CP)....

I powered up a 50% WG/RS Omastar to level 35 and I have maxed a RT/SE Golem so I feel like I'd have used RT/RS Omastar all the time. I also was never able to get my hands on DB/DC Dragonite or ZH/BS Snorlax, though I do have a L/BS one of the latter.

Personally I really want Ice Shard/Icy Wind Dewgong, I know it's crap but that's a killer defensive moveset and since it was garbage before the moveset changes, I bet it's one of the rarest legacy mons out there (excluding Psybeam Chansey etc).

I got a ZH/BS Snorlax at 3053 CP and two Lapras, one with IS/IB and the other with IS/B.

I really want a DB/DC Dragonite, RT/RS Omastar and Exeggutors with C/SoB and C/SeB.

Got close on Exeggutor with a maxed out C/P that was the best defensive move set at the time.

Omastar and Gengar. Snorkel would be nice too.

Shadow Claw and Shadow Ball on a Gengar.

1) Shadow Claw / Shadow Ball Gengar
2) Rock Throw / Rock Slide Omastar

Got DB/DC Dragon & ZH/BS Snorlax; don't mind C/SB egg cause seldom use it....

DB/DC Dragonite. I wish I hadn't walked a Lapras 575 km, I'd almost have enough for another Dragonite evolve.

Plus if I knew the moveset would be removed then I would have tried harder to get it.

Fury Cutter + Stone Edge Kabutops
