I am concerned that the dual lands are going to have me playing a turn behind in some instances. I also have some inconsistency in my 3-drops and I'm not sure which direction to go.

1 Drop

Duress: View hand, get rid of something good. I was going to go Thoughtseize but I think I have enough removal that I'm more concerned with noncreature cards.

Nivmagus Elemental: Still kinda flip-flopping on what 1-drop creature I want, if any. I figure this guy gives me an outlet if anything gets countered or I don't have a Possibility Storm sorcery/instant target, which would then put him outside of Anger of the Gods range. That's a lot of maybes for a 1-drop, but whatever.

2 Drop

Dreadbore: Kill stuff.

High Priest of Penance: Make them hesitant to attack. In an emergency, I could Magma Jet him, too.

Mizzium Mortars: Kills some opponents' win-cons such as Stormbreath or Blood Baron. Overload board wipe. I should probably up the number of these, but with only 7 red lands, I'm not sure I'll ever get a chance to overload it.

Magma Jet: The scry is what's important with three colors. If you have it turn 2, it should kill something, otherwise just smack a player with it.

Nyx-Fleece Ram: Not a sexy card, but between this and Soldier of the Pantheon, I decided to take the Ram because he doesn't die to Anger of the Gods or many other instants, he won't likely be targeted by removal unless he's all I got, and he makes all these shock lands & Underworld Connections hurt less.

3 Drop

Boros Reckoner: Devotion for the gods is nice, but mostly he's a way to stop them from wanting to attack, which gives me time to get to my removal.

Hero's Downfall: Kill stuff at instant speed.

Underworld Connections: Card advantage using life as a resource. Feed Pack Rat.

Athreos, God of Passage: Great card. Early game, the opponent will usually take the 3 life, but later on they'll probably regret it.

4 Drop

Mogis, God of Slaughter: Puts a clock on the other player if I've managed to keep removal steady, and slowly tilts board state in my favor if I haven't. Not to mention swinging for 7 damage himself if he comes to life. Possibly kills other gods.

Whip of Erebos: Might be inconsistent with this deck because it probably only helps me late-game. Obviously, giving Assemble the Legion and Pack Rat lifelink could be big. Oh yeah, and I suppose it makes discarding creatures to Pack Rat slightly less of a pain.

5 Drop

Assemble the Legion: If early removal has gone well, this should tilt things in your favor even if the life totals don't look so good by turn 5. If they have enchantment removal, they've probably used it on your gods or Cauldron by now.

Blood Baron of Vizkopa: I just took out Ghost Dad for this because of his protection from white and black.

Possibility Storm: I know some of you are really confused seeing this one in here, but when I looked over my list it made sense to include this instead of Sire Of Insanity or Rakdos's Return to disrupt control. It will hurt them more than it hurts me.

Creatures: I'm okay with cycling into any of these creatures.

Instants: In plenty of cases, I won't mind swapping Hero's Downfall and Magma Jet.

Sorceries: Not quite as smooth, but if I'm playing a Dreadbore, I can probably find a use for Mizzium Mortars, and vice versa. Kind of sucks to waste Mortars' overload, but it's not the end of the world unless they've managed to develop an army. Getting Duress could be kind of a toss-up if they don't have much of a hand left. Getting Revoke Existence seems like it'd suck, but if you have no other targets, just get rid of your own Possibility Storm.

Enchantments: Very versatile because the Whip and gods are also enchantments. Underworld Connections is the only one I might not want as a late play, but it wouldn't suck either.

6 Drop

Merciless Eviction: An extra board wipe in case of emergency. Costs too much though.

Sideboard

Anger of the Gods: I might need an earlier board wipe.

Bile Blight: Ditto.

Dark Betrayal : There's lots of black currently, why not?

Fiendslayer Paladin : Same as above.

Elixir of Immortality: Makes Pack Rat and shocking yourself hurt less. Side in against mill/control.

Lifebane Zombie : Definite add against white or green.

Pithing Needle: For AEtherling, planeswalkers, etc.

Revoke Existence : Side in if necessary.

Slaughter Games: Fuck up combos and win-cons. Side in for Possibility Storm once you figure out what you really need to get rid of.
