One of my favourites, and easiest to play, is Spore Cry. The main card came from Planar Chaos and is Sprout Swarm. It became the keystone for a Pauper deck, which was quite easy to shift into a Peasant one.

The deck is very straight going : summon one Soul Warden, and then cast Tokens any way you like.

It's quite common to end up with 40 Life points and more.

Here's the list from Patrice Hello, who won the November tourney in Paris.

1 Pendelhaven
4 Terramorphic Expanse
7 Plains
8 Forest
1 Spore Frog
2 Thornweald Archer
4 Essence Warden
4 Kami of False Hope
4 Pendelhaven Elder
4 Soul Warden
4 Fists of Ironwood
2 Ramosian Rally
2 Strength in Numbers
4 Raise the Alarm
4 Scatter the Seeds
4 Sprout Swarm
1 Acorn Harvest

Sideboard:

1 Sundering Vitae
3 Naturalize
3 Prismatic Strands
3 Avoid Fate
3 Wrap in Vigor
2 Thornweald Archer

As you can see, you have plenty of solutions to swarm your opponent, gain life and do the kill. Uncos are Pendelhaven and Pendelhaven elders. You can notice that Terramorphic Expanse is an auto-include.

After the tourney, Patrice made some critics about his own deck, and changed it so :

1 Pendelhaven
4 Terramorphic Expanse
7 Plains
8 Forest
1 Pallid Mycoderm
1 Spore Frog
4 Essence Warden
4 Kami of False Hope
4 Pendelhaven Elder
4 Soul Warden
4 Thornweald Archer
2 Gilt-Leaf Ambush
2 Ramosian Rally
2 Strength in Numbers
4 Raise the Alarm
4 Scatter the Seeds
4 Sprout Swarm

Sideboard :

1 Sundering Vitae
3 Naturalize
3 Prismatic Strands
3 Avoid Fate
4 Wrap in Vigor
1 Pallid Mycoderm

Fists of Ironwood came out, since it was one of the worst token generator of the deck (you basically need one creature at least to cast it). Acorn Harvest is too expensive. 2 Thorweald Archer joined in since it prooved very useful against a bunch of creature (who said "Orni" ?). Pallid Mycoderm is a solution against Echoing Truth and all the Tremor like. Gift-leaf Ambush is a newcomer from Lorwyn, but could be replaced with Echoing Strength.

Any comments welcome !
