Combos Utilizing Vitalize

First cast the Dual nature then cast Verdant Force. Wait a couple of turns to build up your 1/1s which will be faster since you get another Verdant Force from Dual Nature.After you get around 20 to 40

get out a couple of priest of titania's and alot of elves. tap them all, then vitalize. retap them and bring out ivy elemental. i had him as a 120/120. next turn double his power with nantuko mentor.

Tap all the little 1/1's to give the Behemoth +1/+1, Use the Vitalize to untap the little fellas then do it again

tap all creatures with ensnare, untap all your creatures with vitalize then attack

use the squirrel nest to play a squirrel token.tap the token to untap the land enchanted by squirrel nest. after you feel you reached a good number or the max, untap 'em all with a vitalize.

tap firecat to make battlewagon 7/3. tap battlewagon to make it 14/3. play vitalize to untap both. tap firecat to make battlewagon 21/3. attack with 21/3 trampler

Attack , then tap for mana , then use vitalize , then tap again for more mana , then play stream of life with all that stored mana

use jolrael to turn all you lands into 3/3s, then kamahl or overrun to make them huge, then vitalize to untap and attack, sounds more complicated than it is, and is always a fun finisher

You will also need Sneak Attack. Use it to bring out Thundermare, then use Vitalize and attack. Then, use Relentless Assault and attack again. Last, use final Strike. KABLAM!!!

attack with your army < prolly snakes and maraxus if you use the other combos listed> and vitalaize to untap all your creatures so maraxus is full power.
