A Junk deck.
Two game plan here :
The reanimator-like strategy is adapted to Commune with the Gods, we can now pick up a enchantment card. That's why we play some Deadbridge Chant and Whip of Erebos.
The second game plan is a mid-range theme, with high impact creatures that can be reanimated or ""quicly""" played from hand (during the 3-4-5 turn). The Ashen Riders are a great addition, either reanimated or played. I especially like the fact he comes down one turn after Angel of Serenity and allows us to take him out quicly.
The non-reanimator spells are dedicated to destroy threats, and any type of threat, thanks to their versatility.
.
Sideboard is pretty obvious :
Centaur Healer
against aggressive decks.
Abrupt Decay and Hero's Downfall to add more removal (potentially replacing Doom Blades).
Golgari Charm
for versatility, especially countering Rest in Peace.
Sin Collector
and underworld connection against control decks.
.
I don't really know what to think of
Obzedat's Aid
. This card have an incredible value when you can reanimate a Vraska the Unseen or Whip of Erebos or even Deadbridge Chant. The problem is that we have no way to pick it from the library with Commune with the Gods. Maybe a couple of Grisly Salvage or even Jarad's Order can be better... One for the ability of getting a land, the other to fill our hand and graveyard (but we already got many 4 drops) ...
.
Theros rotations ended reanimators decks, i think this list can be very surprising to play against, since most of anti-graveyard-sideboard-cards had been removed from the metagame.
Please give it a try, comments and advices are welcomed ! :)
