Infect infect infect. Beef up your infect guys, get poison counters on the opponent, win the game. That simple.
I believe this deck has many potential combos and each card builds off of the other very well.
COMBOS:
Fireshrieker
+
Phyrexian Hydra
+
Unnatural Predation
Phyrexian Hydra
is a huge fatty when it comes to infect, being a 7/7 for 5, and it can deal a number to your opponent by itself. However, with it's hindering ability it doesn't stay on the field as long as you might want to. With Fireshrieker giving it Double Strike, you don't have to worry about your hydra being chump-blocked to death, giving the Hydra first strike damage. If you chain
Unnatural Predation
with this, your hydra gets +1/+1 AND Trample, and with Double Strike, that can be a game ender right there with one attack with the poison counters alone.
Ichorclaw Myr
+
Mutagenic Growth
Ichorclaw Myr is a pain to deal with on its own. It has a small body on him, so players are tempted to let him pass and take the damage, especially with its ability making him a 3/3 if he's blocked, so in the end you really need a 4/4 to deal with a 1/1 at the very least! If someone tries to block him, chain mutagenic growth and he could take down a creature as big as a 5/5! Plus, it could be played at the very least for 2 life.
Noxious Revival or Corpse Cur + Putrefax or Whispering Specter
Use Noxious Revival and Corpse Cur to keep the good times rolling, bringing back much needed cards from the graveyard. These cards are especially potent with
Putrefax
and
Whispering Specter
. Keep bringing back a 5/4 with infect, haste and trample for cheap to pressure your opponent and make your opponent discard their entire hand with Whispering Specter, making them helpless.
