Green Infection (Modern)

The budget deck, which I'm going to take on FNM. Played and tested online as cheaper version without "Pendelhaven", Inkmoth Nexus or Spellskite... Gaves me plenty of fun and surprises, so I decided to test it in a old-fashioned style ;)
Main idea isn't mine, but I have made some improvements.

Infection is quick. Really quick. If opponent let me stay with my creatures and doesn't counter my buffs - simply dies in 3-4 turn. Sometimes even in second! If he survived first phase, can be hard to beat him in mid-game... But no risk, no fun!
Deck can be played as showed, but maybe needs some more balance between spells and creatures.

Main strategy is to put as fast as possible one little creature, swing for attack and pump it over +10/+10 (if blocked - with trample). Easy to understand, but acurate timing of casting spells is crucial. Will I be countered or not? Is he having a removal in his hand? Use this land now, or wait with hexproof in hand to the next round? These questions you will ask yourself many times playing this deck.

Turn 2 kill:

1. Forest, than Glistener Elf;
2. Forest, than Might of Old Krosa (in main phase), Groundswell (benefiting from landfall) and Mutagenic Growth payed with life. Elf will gain lethal impact...

Turn 3 kill:

1. Forest, Llanowar Augur;
2. Forest, Ichorclaw Myr or other creature with infect;
3. (Upkeep) Sacrifice Llanowar Augur on Myr (Myr get trample and +3/+3), than play Forest, pump him with steroids and attack for victory!

Rest of cards are mainly for increase survival of your sensitive cratures if first plan of 2-3 turn win failed.
Main deck:
Glistener Elf, Ichorclaw Myr, Necropede - contamination carriers.
Llanowar Augur - wall for first turns and steroid with trample for infection creatures.
Inkmoth Nexus - last resort when you have no creatures on battlefield.
Pendelhaven - defence against damage spells on creatures.
Rancor - trample (very significant) + additional power.
Wild Defiance and Livewire Lash - get the maximum from your spells and keeping you opponent away from targeting your creatures.
Giant Growth and Might of Old Krosa - simply steroids, but they also can counteract damage spells.
Ranger's Guile - hexproof.
Vines of Vastwood - hexproof and steroid, when kicked.
Predator's Strike - steroid with trample, but quite expensive.
Lightning Greaves - hmm... maybe it will land in Sideboard.

Sideboard:
Corpse Cur - if you know that probably you will lose couple of your creatures in first few turns...
Dismember - against midrange opponents creatures.
Nature's Claim - agains artifacts, enchantments and ramp decks.
Pithing Needle - against combo decks, mills etc.
Spellskite - against enchantments and control decks.
Tormod's Crypt - against black and red decks.
Wild Defiance - maybe to put one more this time? ;)
