Saproling decks are the closest you can get to afk farming in Magic, but it's fun as hell imo.
You can also build this at a very small budget if you spare out Tendershoot Dryad, Pendelhaven, Descendants' Path, Realmwalker and some Psychotrope Thallid. You can exchange them for more Thallid Shell-Dweller and something like Fungal Rebirth, Fecundity, Verdant Embrace or a Rot Shambler.
You want to get your spore production up and running as soon as possible. Sporoloth Ancient, Sporesower Thallid, Winding Constrictor and Tendershoot Dryad help you increase your saproling output. If you get any two of them down early on you have a good chance to snowball down the rest of the game. When you have enough saprolings you should be able to overrun your opponent with the help of Sporecrown Thallid, Tendershoot Dryad or a Mycoloth. Strength in Numbers and Return of the Wildspeaker give you the oppertunity for a final blow. Also Slimefoot, the Stowaway burns all your opponents when you sacrifice saprolings for your abilities.
Your main weakness is the early game. Bone Splinters, Disfigure and Sundering Growth allow you to destroy threats to your fragile economy in the first few rounds. With Thallid Shell-Dweller you can block most incoming attacks early on. Deathspore Thallid additionally lets you remove small creatures in early game, but scales well into late game to crush any big creature as soon as it enters the battlefield.
Your second weakness is board wipe, but theres no real solution to that here. With Night Soil you may be able to salvage some saprolings. Slimefoot, the Stowaway will at least still trigger for all your lost saprolings and makes a board wipe more painful for yopur opponent. But besides that you have to practically start at turn 1 again. If you know a good way to protect yourself against a board wipe with this deck please let me know in the comments.
So have fun at the kitchen tables with this G/B casual fungi deck!
Edit:
Obvious combos are either Sporesower Thallid + Sporoloth Ancient
or Sporoloth Ancient + Winding Constrictor
, which both give you one saproling per fungus per upkeep. If you get Sporesower Thallid + Winding Constrictor
down at the same time, all your fungi will produce 4 counters each turn. Winding Constrictor will trigger once for a fungus itself and then again for Sporesower Thallid. When you manage to get Sporoloth Ancient down additionally, that means 2 saprolings per upkeep per fungus!
At that point your opponent shouldn't have mushroom to turn the game around...
