Combos Utilizing Saproling-Symbiosis

First you use Jolreal

feed the devourer the saprolings for an uber fungus!

feed the farmer the saprolings for an uber fungus!

cast symbiotic wurm, fling it for 7 damage, and cast sproling symbiosis to get 14 saproling tokens

You'll have several 2/2 creatures with Verdeloth and Verdent Force, play Saproling Symbiosis, and have twice as many 2/2 creatures. Saproling Cluster optional, just incase you're low on mana.

Get out tons of little guys with a Haunted Crossroads/Avatar combo and then double the amount you have with the Symbiosis.

use Nemata, Verdeloth and Rith to get lots of 2/2 sprogs, cast the symbiosis and get more, sac these to make your sprogs that can attack really big, and you win!

play d.h., attack with rith, choose black, then play the evolution 'n' symbiosis, and lookit all your sap.'s!!!

have at least 6 creatures out on the field, play saproling symbiosis which multiplies the number of creatures u have by 2, so that u will have 12, play phyrexian dreadnought and sacrifice the tokens.

Great against artifact decks. Gain enough 1/1 insects from Roothold (about 5-7), then use Saproling Symbiosis to double your creature count.
