Gnatcrifice

Kill your annoying gnats and get huge soul eaters quickly, just try not to die in the process ^^

Weeping idol will generate a lot of faeria as your gnats die, giving you plenty of time to heal and build towards your souleaters, you have a lot of heal so don't be afraid to hit into your opponent creatures with the gnats to buff your soul eaters if you have it in hand.

It's hard to survive until you have all the lands for soul eater but the pay off is great:

Mulligan: you want to start with a gnat in your starting hand, the next best thing is smile (to find it) or story teller.
keep doomgate / other sac cards if you have a gnat in hand.
Dream hand: Gnat, doomgate, demon wrangler/weeping idol.

Have fun!
