Add some more Lightning Strike and make the deck more consistent. For your good creatures like Courser of Kruphix , Fanatic of Xenagos , Ghor-Clan Rampager and Zhur-Taa Druid , up their numbers to 4. Try Burning-Tree Emissary as well. Some less good cards you could get rid of first would be Ruination Wurm , Skarrg Goliath (too expensive mana-wise) and Destructive Revelry . Nice deck!

you shouldn't have a Ember Swallower in your deck,they're to costly and get rid of your lands for a great cost and with some decks they can get out 3 lands in one turn and get even more with out a problem and leaving your deck 3 turns behind with mana.

Sylvan Caryatid is pretty good.

yeah its really good if you need extra mana

OpenFire do you have any advice for my Lord of the mana flooded void deck?

It looks like you have different mechanics going on here. If you want to use xenagos in his x/x capacity the. I would suggest you speed up your deck with elvish mystics and the caryatids. The caryatids will help with early blockers against the speedy aggro decks as well. I would use beefier creatures also, look at my deck 30/30 trample haste, what?!?!. Most of my creatures have haste to begin with and I also have some really nice combos with the hydras and dragons. My best one of course is having the worldspine wurm out on turn 6 or 7, depending on the draw, attacking for 30/30 trample and haste, hence the name.

Thank you OpenFire , crazycreeper55 and Lacken ! I have made a couple of adjustments already, and will make a couple more based on your suggestions once i get the proper cards. Sylvan Caryatid is the card i'm looking forward to getting a hold of, i believe it will serve a huge purpose in my deck.

Caleb09 try putting a Savageborn Hydra in your deck,its a very good hydra with double strike

Caleb09 do you have any advice for my Lord of the mana flooded void deck?

Yeah i agree with you crazycreeper55. I've been looking for some Savageborn Hydra 's but havent found them
