Primal rage if you want trample
Battlewand oak is great for more aggro as well
take out lurking predators add reach of branches.
hurricane or squall line over raking canopy anyday with orchard warden they can be another potential win con.
Take out urborg, switch with murmuring bosk switch kormus bell with life and limb which turns all forest into 1/1 saps in addition to their other types. Put in 1 or 2 nemata, grove guardian, put in sheltering ancient, cradle guard, and weatherseed treefolk. Put in reach of branches take out all other artifacts put in more creatures like leaf-crowned for aggro, dauntless almost all forests and treefolk make him ridiculous, harbinger to get your best trees to you quickly, bosk banneret for quick big creatures to get out there, orchard warden for ridiculous life gain. For destruct try armageddon and wrath of god, for flyers and little creatures try kusari-gama or windstorm, hurricane, squall line. Verdeloth the ancient is amazing too add more forest saps then increase their power. Woodfall primus, wickerbough elder and rootgraple for enchantments and artifacts and woodfall and root deal with lands as well. everbark shaman and everbark shaman for saproling accel, heartwood storytell and sapling of colfenor for potential drawing. Deadwood treefolk to bring back from grave. Indomitable ancients for potential blocking. Chameleon colossus for a potential forest saproling treefolk protection from black and indestructable and all other creature types its crazy. Door of destinies or coat of arms for extreme power. The cool thing is that most of this are treefolk so they work perfectly with leaf-crowned elder. This is actually more or less how my legacy treefolk deck is, but this was just an overview of many of the cards that could make this kind of deck better and different. If you end up adding a lot of baddies with big toughness then pop in doran and unstoppable ash. If you keep the deck like it is I would suggest fendeep summoner.
