ESPRcon

I think you are right. It seems that if UB gets behind they cant do anything about it. I really like draw go, but this more proactive strategy seems better

I would swap out: Frost Breath and Deceiver Exarch. Frost Breath because it doesnt get rid of the problem and deceiver because it seems more like a combo piece and not a defensive creature. I would play wall of omens instead.

maybe some counterspells like mana leak or dissipate

prehaps Aven Mindcensor? I am not sure, honestly I dont know

it seems like a good tweek, I would stick with putrid imp though since its a discard outlet and it can be used to flashback cabal terapy later on. just my 2 eurocents

sun titan seems a little misplaced with only 20 lands but otherwise it looks good

nice domain zoo list. Have you considered KotR ? when is might of alara sided in?

Breeding Pool

This looks like a good zoo deck. I assume that the reason for watchwolf over tarmogoyf is budget, if not then i would definatly add tarmogoyf. I would swap the shocks with lightning helix, since a little lifegain with all your shocklands should be good.
But overall ill say it looks like a good deck

I would add the UG ravenica dualland. Other than that it seems good

I just dont think thrun is fast enough for vintage, but i may be wrong. It seems like the blue controldecks mainly win with tinker -> Blightsteel Colossus wich thrun does poorly against.

I would add more lands. A control deck needs +22 lands imho.

I would add polymorph and take out all the ramp creatures. The creature needed for polymorph is generated by awakening zone and you could also play that green land that CiPT but gives you a 0/1 token.
The deck idea is cool

I would cut the fogs for more creatures but thats my opinion.

You might be right, but they also play tinker wich thrun does nothing against

since this is written as Tournament Quality ill say that Wheel of Fortune is banned in legacy. Othervise it seems pretty good. I would add 4 goblin guides and 4 keldon marauders and cut the spark elementals.

I would cut some of the auras and play more creatures and HotP's

yes but how are they going to answer duress? Fow'ing is not a good idea and duress cost's B and thrun cost GG2. I think its to slow.
I am not saing its a bad idea, im just curios to hear your reasons.

nice idea but why Mishra's Bauble?

If this is to be considered Tournament Quality legacy elves it NEEDS the Heritage Druid+Nettle Sentinel+glimpse of nature combo.
But the deck itself seems fine
