Aristocrats with a human sub-theme.
Set up the board early with human weenies, then finish with an aristocrat or spirits, while having some slight control elements throughout.
Champion of the Parish - the ideal turn 1 play. Every creature after him besides Falkenrath and spirits will buff him up for early damage.
Doomed Traveler - buffs Champion and is a good blocker or sacrifice target.
Cartel Aristocrat - sac outlet that also buffs the Champion and can protect itself. It can produce significant damage if it has enough sac targets for long enough.
Zulaport Cutthroat - yet again buffs up the Champion and is good life drain with the sac outlets in the deck.
Falkenrath Aristocrat - the big finisher in the deck. Once it hits the field, it can be very hard to get rid of, especially with all of the humans that will be making it huge.
Kolaghan's Command - every option can be relevant and powerful at any time really.
Lightning Bolt - because why not? Can help finish or be removal.
Path to Exile - just really good removal.
Gather the Townsfolk - great if combined with Champion and Falkenrath, but also can be useful just as fodder for blocking/life drain.
Lingering Souls - a better token generator than Gather the Townsfolk. It doesn't have any human synergy, but the tokens themselves can be a big threat with flying.
Return to the Ranks - most of my creatures cost 2 or less, so this can create explosive plays. Tokens and weenies can also help pay for it, which helps.
Suggestions are appreciated, and +1 if you like it!
I haven't made a sideboard yet, so suggestions for that are also welcome.
