As thallid/saproling decks go, this is probably not too pricey. However. it is also a little lighter on traditional creatures than may of its counterparts. I nearly balanced the green and white, which is a challenge, but the inclusion of Intangible Virtue and Phantom General (as well as Murganda Petroglyphs), makes populate and Saproling Symbiosis all that much better. Pariah is in to take out a big creature, such as a 12/14 flyer that gets more +1/+1 counters from effects. By itself, it lives forever; otherwise, multiple things have to come in, not hurt, and then kill it. The 9/15/3/13 curve averages 2.50, and the 1-spot really lacks good creature options. I also was surprised by the drop at the 3-spot, but it just didn't have things that worked in the end.
