Just remember now you will be arch enemy and become targeted no matter what because of poison/infect. Even I am against it but however lets see what we can do to help you along. Now your Commander is how you draw cards while your removal is mostly aimed at flyers. First with poliferate lets look at Thrummingbird which is a 2 drop flyer that poliferates as it hits. I am not sure if you'd be interested in Contagion Clasp and or Contagion Engine. Then the over run effect of Triumph of the Hordes as well. Since you are against flyers while this cost 6 mana it would deal with all opponents flyers which is Archetype of Imagination. Things to help protect your board are things like Asceticism, Heroic Intervention and Saryth, the Viper's Fang. More for your ramp you could use Sword of the Animist which is very reliable to just equip since you are attacking to get you lands. You could use this just to make a small army as well which would create flyers to do incrimental damage or block with which is Feywild Visitor. So in essence with this type of deck you have to be fully aggresive with some defensive moves to stay alive while garnering all the hate.
I opted to use
Tainted observer and
Viral Drake over
thrummingbird. While
contaminant grafter is a 5 mana drop i think the three do the job.
While
Contagion clasp and
contagion engine are nice i felt that
decimator web and
karn's bastion for repeatable active proliferate would suffice as they are more efficient in mana cost. I also have
evolution sage and
flux channeler for passive proliferation.
In addition i have
serum snare,
smell fear,
carnivorous canopy,
mesmerizing dose,
reject imperfection,
fuel for the cause as removal that doubles as proliferate. Included is
contentious plan,
experimental augury,
steady progress,
tezzeret's gambit and
vivisurgeon's insight as card draw that doubles as proliferate.
Inexorable tide doubles all of these bonus spells with
planewide celebration giving me x4 proliferate for 7 mana instead of another "over run" like
triumph of the hordes. I have
tekuthal, inquiry dominus to double every proliferate passively.
Due to this i wanted to keep as many
Toxic/ infect creatures as i could that also activated proliferate. With the total sum i do feel that i have enough proliferate triggers in the deck.
I have
manifold key,
prowler's helm,
suspicious bookcase,
whispersilk cloak and
rogue's passage to give unblockable with a bonus
blighted agent and
spinebiter To ensure delivery of poison counters with
infectious bite and
prologue to phyresis. So with the infect/
toxic crew i feel that their total sum is enough poison triggers in the deck.
Venerated rotpriest helps as well. Plus i have
decimator web to trigger poison unwilling on my victims.
I utilized
broken wings,
carnivorous canopy,
return to the earth and
shoot down as removal for flying/ artifacts/ enchantments as the choice of either three i find to be valuable.
raking canopy as a bonus against flying.
I would love to add
asceticism but i am unsure which card to swap it for, and i dont want to unlikely scenario of having it counter my own
venerated rotpriest trigger. Still
asceticism would make a great addition, which card would you suggest swapping it for?
I was thinking
wandering archaic, however i enjoy the flavor of this card a lot.
Omnath, locus of mana,
kruphix, god of horizons and
seedborn muse will amplify my use of the card draw i will have so i would like to keep those. I could always drop
blight mamba or
cystbearer.
