Fungus doesn’t think or sleep—it just spreads and devours. The “Fun with Fungus” deck lets you take the reins of a post-apocalyptic rampage of Thallids, and these freaky fungus fiends won’t take “Eeeeewww!” for an answer.

In the early going, play as many Thallids as possible so they can start building up spore counters. Waiting three turns for enough spore counters to make a single Saproling might seem slow, but when you have three or four Thallids budding at once, you’ll soon have more creatures than you know what to do with.

Don’t be too aggressive in combat with your early Thallids. Trade with an opponent’s creature only if you really need to get it off the table. The longer your Thallids stay in play, the more work they’ll do for you. You’ll be rewarded if they’re still around when Sporesower Thallid Buy or Verdant Embrace Buy turbo-charges your Saproling production, or when Thelon of Havenwood Buy makes your Thallids enormous.

To get the most from your Saprolings, you can attack with them or you can sacrifice them. Attacking is good if your opponent has few blockers, and it’s especially good if you have Pendelhaven Elder Buy to pump them all up at once. If that’s your plan, it’s best to create Saprolings as early as possible.

If you can’t attack, use your Saprolings as blockers and sacrifice fodder. In this case, don’t create them until you need them. Your opponent will have a harder time removing spore counters than destroying 1/1 creatures, and if Thelon shows up, you’ll be glad those spore counters are still there! The “Fun with Fungus” deck is packed with effects that take advantage of a sacrificed Saproling. Make a creature bigger with Thallid Germinator Buy or smaller with Deathspore Thallid Buy. Regenerate a Thallid with Savage Thallid Buy. Gain life with Claws of Gix Buy by sacrificing any permanent. Sacrifice three creatures to pay Dread Return Buy’s flashback cost. And a creature enchanted with Fallen Ideal Buy can devour all your Saprolings—and your other creatures—to become big enough for one gigantic, game-winning attack.

After playing with the deck, customize it. More copies of Thelon of Havenwood or Sporesower Thallid will increase the deck’s power. Try the Time Spiral cards Sarpadian Empires, Vol. VII Buy or Thelonite Hermit Buy to generate more Saprolings. But the best (and most fun) option may be the Ravnica card Doubling Season Buy, which doubles both the number of spore counters you get and the number of Saproling tokens you put into play!
