Built this when I saw Midnight Guard + Presence of Gond. It runs (effectively) 12 fogs and uses Timberwatch Elf / Chorus of Might as alternative win conditions.
Might look into Standard Bearer to protect your combo. Also Devoted Druid and Sigil of the Nayan Gods can combo nicely with Presence of Gond (also makes inf. Creatures). Sigil has the added benefit of cycling when you don't need it.
