Thallid Retriever

At the beginning of your upkeep put a spore counter on Thallid Retriever.
Remove three spore counters from Thallid Retriever: Create a 1/1 green Saproling.
Sacrifice two Saprolings: Return target creature card from your graveyard to your
hand.
Most life cycles reach their end by becoming Thallid food. -Doran Hurk, Mycologist
