This deck is about poisoned your enemy first then proliferate the poisons counters on him ! Easy :)
First move
First, you need to go face with an infect creature, like
Glistener Elf
or
Blighted Agent
to give your opponent a poison counter.
After, if you can go face again, use
Courage in Crisis
to do 3 poisons counter more (two from the two +1/+1 counters on the infect creature and one from the proliferation of the counter on the player directly). The land
Soaring Seacliff
helps to hit the plyer directly.
Midgame
If you have to go in midgame/lategame, just blick your
Pollenbright Druid
or
Bloom Hulk
with
Ghostly Flicker
or
Teferi's Time Twist
to add more and more poison counters that are at least unremovable. That a good way to protect your creatures also.
If you are in some trouble on board, remember that you can also proliferate the -1/-1 counter on opponent’s creatures made by your chump blocking infected creatures or by your attacking
Ichorclaw Myr
.
Mana base
The mana base is a bit tricky, but
Hickory Woodlot
and
Saprazzan Skerry
works perfectly in the idea of the deck ! You can add a counter on it each time you proliferate.
Like this,
Fuel for the Cause
that is maindeck can be played with only two mana and then put back a depletion counter on this two lands like nothing append (and you add a poison counter to the opponent in the move).
Same things,
Pollenbright Druid
or
Bloom Hulk
can be played "for only one and two mana". But if you can play those cards with basic land, do it instead.
Some tricks
Don't forget that
Ghostly Flicker
can blick a land, like
Hickory Woodlot
and
Saprazzan Skerry
to get back the counters on it or
Soaring Seacliff
to get fly. Also,
Teferi's Time Twist
is a good way to protect your
Blighted Agent
during the opponent turn cause you can attack straight after with him being a 2/2 unlockable that you can proliferate for more poison counter. It’s also a good kill move. Each time you proliferate on
Blighted Agent
you add one poison from the +1/+1 counter and one from the proliferation’s effect.
About the matchup
If a creature who proliferate is countered, you lose the proliferate effect and the depletion counter that you’ve used if you did so. You also need to do at least one infect's damage to the player, maybe against burn it’s hard, that why I've put
Corpse Cur
maindeck. I don't know about aggro.
Indeed, the fact that proliferating is enough to kill, it works well against Frog’s deck.
WIP
The side and the deck need to be more tested.
Maybe need to add some card draw/filter.
I'll probably cut some lands
