1x Sprout Swarm

2x Heartbeat of Spring
2x Phyrexian Altar
2x Ashnod's Altar

I like your List, Volfortis, but I'd run it like this, as it can draw your deck and produce infinite hasty saproling tokens by turn five with a perfect draw.
Token doublers:
4x Parallel Lives
4x Doubling Season
These enable the production of many, many tokens; more than 1:1.
Token Generators:
1x Sprout Swarm
1x Saproling Symbiosis
2x Nemata, Grove Guardian
I dropped this to one swarm, as we'll be drawing into it, and one symbiosis, as it can be cast at instant speed to prevent an alpha strike from the opponent, especially without durdling around with convoke. Sprout Swarm is in because it's broken as hell with multiple doublers out, and Nemata is a good mana sink.
Mana engine
2x Heartbeat of Spring
2x Phyrexian altar
2x Ashnod's Altar
We need mana to dump into spells, and sac outlets to use as part of our draw engine. Heartbeat is a good backup plan, allowing us to use lands more efficiently
Card draw engine
1x Psychotrope Thallid
4x Fecundity
Fecundity reads, once you've a sac outlet out, "sacrifice a creature: you may draw a card." We'll be using this to draw through to the rest of our deck.
Mana dorks:
4x Llanowar Elves
4x Elvish Mystic
2x Birds of Paradise
The proportions can be altered, but 10 1-mana dorks is pretty much essential to getting out fast: they can be sacrificed to altars after they tap for mana, too, once you start to go off.
1x Mycoloth
Sometimes you can't get there in one turn, so here's your backup plan.
1x Overrun
1x Vitaspore Thallid
What's better than a swarm of 1/1s? A hasty trampling swarm of 4/4s!
I'll try to keep it Legacy-legal, so I'll skip the Strip Mine, but if you want to use them, swap out the
4x Jungle Basin
for 4x Strip Mine
4x Ancient Tomb is nice, but they can easily be swapped for forests
16x Forest should get you the rest of the way there.
Tappedout.net linkI run Ghave tokenswarm in Commander, so I've got a pretty good idea of how to get there.
Ideal hand:
Turn 1:
Forest, Mana dork
Turn 2: forest, heartbeat of spring
Turn 3: Forest, mana dork, Ashnod's altar, fecundity
Turn 4: Float mana off of mana dorks, sac to A's altar, draw two cards, Forest, cast doubling season, cast Swarm with buyback, sac to A's altar, draw cards, cast P. Altar and another Doubling Season.
Turn 5: Swarm/buyback, sac to altars to draw cards, play forest, play Nemata, generate Infinite tokens while casting your entire deck. Cast Vitaspore Thallid, sacrifice half of your thallids to give the rest haste, and then cast overrun. Win hard.
I'd take my time going off, though. Probably turn 6 or 7. I think there's a faster way to get there, though.
