Sporecrown Thallid
Oracle Text
Each other creature you control that's a Fungus or Saproling gets +1/+1.
Card Rulings
4/27/2018 Because damage remains marked on a creature until it’s removed as the turn ends, nonlethal damage dealt to a Fungus or Saproling creature you control may become lethal if Sporecrown Thallid leaves the battlefield during that turn.
4/27/2018 If a creature is somehow both a Fungus and a Saproling, Sporecrown Thallid’s ability gives it only +1/+1.
Tribal fungal support that isn't aimed at making tokens faster, though...
Color me intrigued.
