This is currently my strongest deck, and is perfectly capable of comboing off by T5. The game plan is to get Selvala, some untap effects, and a mana sink (preferably Omnath or Hero’s Bane) into the same room, and watch the fun. There’s tutors and draw spells to get missing components, Haste and Trample enablers to make the kill easier, and some assorted utility effects.

A sample game might look like this.

T1
Play Forest.
Tap Forest for G, cast Llanowar Elves.
T2
Play Wirewood Lodge.
Tap Forest, Wirewood Lodge, Llanowar Elves for 1GG, cast Selvala.
T3
Play Forest.
Tap 2x Forest, Llanowar Elves, Wirewood Lodge for 1GGG. Pay G to Selvala for GG (1GGGG floating), cast Hero’s Bane (4/4).
T4
Tap Llanowar Elves for G, cast Quirion Ranger.
Tap Forest for G. Pay G to Selvala for GGGG, double Hero’s Bane for 2GG (8/8)
Return tapped Forest to hand with Quirion Ranger to untap Selvala.
Tap Forest for G.Pay G to Selvala for 8 green, double Hero’s Bane for 2GG (16/16) (4 green floating)
G from floating to Wirewood Lodge to untap Selvala. (3 green floating)
G from floating to Selvala for 16 green. Double heroes bane 3 times for 6 generic and 6 green (128/128). (6 green floating)
1G from floating to cast Primal Rage, 3G from floating to cast Fungal Sprouting, creating 128 1/1 Saprolings. (0 floating)
Attack for lethal against an opponent, then continue around the table as neccessary.

Note that I assume the T4 lad drop is missed, and casting the Quirion Ranger T1 would only move the game back by one turn, with an opportunity to cast, say, Priest of Titania on T2.

After some more goldfishing, I may just set this deck aside as an example of What Not To Do.

Having a 274,877,906,944/274,877,906,944 Hero's Bane and casting Fungal Sprouting on it (on T7) is maybe not the game I want to play.

That's friggin' awesome. I respect your self restraint but that seems fair to me, even for my casual, anti-combo playgroup.

Depends on the consistency, I think. And judging by the decklist, it seems consistency won't be an issue, with several redundant combo pieces and engines.

At the same time, I'm not sure goldfishing does the deck justice. I think it's worth testing how well the deck stands up to disruption and removal, which at this point seems like it could swing either way. Maybe try to proxy the deck with the playgroup, see how it holds up.

Maybe Asceticism, Archetype of Endurance and/or Spearbreaker Behemoth to protect your creatures? Last two work with Selvala, too.

I've added Asceticism, but not updated the list. Current foci for improvement are resiliency and consistency., both of which were negected in the first draft. Will get my first real games in tonight.

Do let us know how they go... I have a Yisan deck currently, with no infinite combos, and no Craterhoof Behemoth... figured that would be enough to tone it down for my group, and I figured being interacted with would also make a big difference... but so far my experience is, I tend to just goldfish Yisan even when there are three other players. My group does NOT shy away from removal, but the deck just doesn't seem to care much. I can handle Yisan dying once or twice, and the games don't last long enough for him to die more often than that.

Anyway, point being, my attempt to casual-ify Yisan is not a stellar success, and Selvala is the first Green Legend aside from Yisan that I find interesting, so I've been optimistic that I could swap over to Selvala and get the power level back down to where it fits my group better.

Sorry about not replying to that - I assume you’ve discovered the answer by now. She’s nuts.

So I’ve been reading up on legacy elves, which seems to play in a similar manner to this deck from an untap effect point of view. The question came up: is Elvish Visionary good enough to include as part of the untap package on the off chance it’ll intersect with Wirewood Symbiote?

Edit- geez. I need to update the OP.

100% Even if you don't get to bounce it, running out of cards while you are tapping for lots of mana is the quickest way to stop the chain. Beast Whisperer is also huge game (probably obvious I know).

Yes, I need to locate one or more Beast Whisperers.

OP updated. No change log, because its extensive. Mostly i doubled down on the things the deck wanted to be doing.

One minor thing, I would without hesitation replace Sylvan Caryatid with either Arbor Elves or Boreal Druid. Sylvan does very little to help Selvala get out earlier, and it isn't an elf so it doesn't synergize with Priest, Archdruid, or the Packmaster.

That’s probably correct.

Not sure why I ended up with the Caratyid, honestly. Maybe I wanted resiliency, so hexproof? Boreal was in there at one point. Probably I’ll end up with Arbor Elf so I can still play Selvala of a forest and a utility land.

If the deck plays like Legacy Elves, maybe you should try Glimpse of Nature.

Patron of the Orochi - seems expensive for the effect
Instill Energy - lets you get 2 for 1'd
Nature's Chosen - lets you get 2 for 1'd

If you remove some the redundant combo pieces and put in more reactive spells the deck would goldfish less and be more interactive. Beast Within and Krosan Grip come to mind first.

Also, Heroic Intervention could help you protect the combo.

I noticed you're playing Burgeoning but not Exploration or Azusa, Lost but Seeking or Oracle of Mul Daya or Wayward Swordtooth. Any reason?

More than likely ill throw a couple Beast Whisperers onto my next order instead.

Patron allows me to reset... almost everything. Selvala, Priest of Titania, Seeker of Skybreak, and similar. Just the Quirion Ranger and Wirewood Lodge types get missed. Also, by the time pay to double Hero’s Bane once, the untap pays for itself. As for the other two, I’m willing to risk it for one drops.

At one level, the lack of reactive spells is a choice. I’m wary of playing a version of this deck that CAN protect itself effectively, because it’s already so blindingly fast and powerful. Passing turn on T5 with a 256/256 because no haste enablers are online and getting blown out by a Wrath is fine. On a different level, a deck that can and does combo off on T5 cares less about protecting itself than one playing for a long game.

That said, more interaction is often good in itself. I’ll have to see whether I feel I can work in a few spells. The two you mentioned would definitely be at the top of that list.

Space, largely. The rest fell away due to not enough impact in the extreme early game where this deck likes to play. T1 Burgeoning is as good or better than a T1 Llanowar Elf, in terms of ramp. After Selvala hits the table, an extra land here or there won't even be noticeable.
