I found this deck on mtg salvation, I thought of building it and trying it out on my own, and then modding it according to what I prefer.
Here's how it works :
WINCON
Avenger of Zendikar
Get a bunch of plants out, pump em up with droppin' lands, attack and win.
Rampaging Baloths
A little less effective than the Avenger, but it still is a neat source of beatsticks.
Worm Harvest
with this card, you should aim to getting lands in your graveyard, with Harrow or Scapeshift and then you keep casting this spell each turn that you have a land in your hand to discard. and at each time, if you have an Oran-Rief, the Vastwood , then you can pump them wiggly worms, and swarm your opponent.
Scapeshift
Gets lands in the graveyard for Worm Harvest , allows you to get the fancy lands, such as Oran-Rief, the Vastwood to pump creatures, or Khalni Garden to get moar creatures, plus it allows fo MASSIVE triggering of the landfall of Avenger of Zendikar and Rampaging baloth and even if ya don't have any of those out, it allows you to remove lands and increase your chances of drawing one of those guys.
Akroma's Memorial or Eldrazi Monument
It's pretty straightforward.if you have creatures, your plants or beasts or worms become a bunch of superman.
LAND FETCHERS
Harrow
Triggers 2 landfalls, gets an aditional land, plus sends one in the grave for Worm Harvest . and the two lands don't come in tapped, so you can cast another land fetcher, like the next one here:
Sakura-Tribe Elder
costs 2, gets you a land. perfect guy to cast turn 3 after you do a Harrow because it'll help with the next one:
Khalni Heart Expedition
best turn 2 drop. cos in turn 3 you do harrow+ land drop or do a Sakura-Tribe Elder , and you instantly get the 3 counters, and get 2 more lands.
Search for Tomorrow
Cast it for the suspend early game, and cast it for regular cost later when you have the lands. cast it on turn one, and have it ready for turn 3 when you do a Harrow and get the Khalni Heart Expedition going.
Wood Elves
Just a landfall trigger to do when you don't have anything to cast really. Plus they're a meat shield for when you lack the plants.
SUPPORT
Harmonize
Draw 3 cards.
Useful like no tomorrow to get them cards you want.
Regal Force
Pop him out the turn after an Avenger of Zendikar / Worm Harvest and your hand will be fat.
Beast Within
Plain old removal.
Terastodon
Removal + a neat beater.
If ya want you can bust some of your own lands for extra creatures and beef up the amount of worms you get with Worm Harvest
