Faeria

Note: Doing this in a practice game won't count, I did it on a wild mission.

I basically used a yellow deck and powered all the "ouch" off of Altar of Souls. Just flood the board with 6/1's, gain life where you can, then once you've topped 20, slug the PC in the face with various 6/1's or bloatflies or whatever presents itself. It almost plays like an old Kjedoran Outpost deck for my 90's Magic players.

2 x Roaming Yak
2 x Shimmering Statue
3 x The Emperor's Command (Mostly for the 4 life)
3 x Healing Song
1 x Laya, Lady of Sorrows
3 x Soul Drain
3 x Altar of Souls (I really wouldn't have more than 1 in play, maybe play the 2nd if that's the 20th point of damage or you're choking on lifegain)
3 x Vile Bloatfly
3 x Shaytan Assassin
3 x Air Elemental
1 x Aryana, Soul of Gagana
