Chatterfang goes Chatterbang - and on opponents nuts (EDH / Commander) [Revision 4]

Strategy:
Keep opponents low with Dictate of Erebos and Grave Pact until you finish with some Combo or Tainted Strike on Slimefoot, the Stowaway and sac some Saprolings.
Combo #1 Ashnod's Altar + Doubling Season / Parallel Lives + Slimefoot, the Stowaway + 2 things to sacrifice or mana 4 open = infinite damage. Sacrifice 2 things to generate 4 mana or tap your lands and then make a saproling with Slimefoot, the Stowaway s ability and thanks to Doubling Season / Parallel Lives you get 2 saprolings that you can sacrifice to generate 4 mana and continue with the loop to kill your opponents.

Combo #2 Ashnod's Altar + Zulaport Cutthroat / Slimefoot, the Stowaway + Jade Mage + Pitiless Plunderer + 2 Colorless and 1G or 1 thing to sacrifice = infinite damage. Similiar to combo #1 combination of Ashnod's Altar and Pitiless Plunderer lets us gain 2 Colorless and 1G for each things we sacrifice and use that 2 Colorless and 1G mana to make saproling with Jade Mage to create infinite loop.

Combo #3 Slimefoot, the Stowaway + Any sacrifice outlet with 0 mana cost or that can sacrifice multiple things at once + Doubling Season / Parallel Lives + Pitiless Plunderer = dying saprolings generates 2 treasure tokens and saproling tokens comes in as doubles so 4 mana to create 2 saprolings to generate 4 treasures and loop away.
