need help with making it more controlling, consistent in drawing the right cards and more towards the competitive side. I also have trouble winning games with this current layout.

Hi - some advice are about to be given, but if you don't like them then, by all means, disregard - no hard feelings :-)

The deck itself seem to center around tokens and a lot of sacrifice. The land base is a little off, but I'll get back to you on that later on.

Since you're going to be sac'ing a alot of critters, I'd highly recommend Fecundity - You'll get card draw like hell. True, your opponents too, but it will not help them much since your critters pack a heavy punch AND you have Sorin Markov. Also, with Fecundity your High Market becomes: Sacrifice a creature (tokens come in handy here), make opp's sac ( Grave Pact and Dictate of Erebos ), draw a card, gain 1 life.If you're still not happy with your opponents drawing cards, Underworld Dreams could be added, however it's -heavy

Your average Converted Mana Cost in the deck, is 3.45 - on that base alone, I'd suggest Unearth and if you feel like it Exhume both can be extremely powerful tools in re-animation and the politics of EDH

Along side the sacrificing, a few creatures could help you, controlling the board doing so, Bloodghast - expensive, but it just keeps coming back, even of you have a small amount of landfall triggers, also a key card to combo with Skullclamp. Nether Traitor comes in handy. If you have a large budget to spend, then Vengevine is a good choice, you could sac it, Birthing Pod it, kill it for sports and yet it will still return to serve.

If your finding a need to get more Experience Counters, then the two Proliferate machines, namely: Contagion Engine , and Contagion Clasp can help with that

Cards to maybe re-think:

Elves of Deep Shadow instead, Birds of Paradise

Elvish Pioneer you'd be better of with City of Brass

Wood Elves you haven't many shock/duals in here, I'd say, cut it for another Swamp

Llanowar Elves - a copy of Nykthos, Shrine to Nyx is nigh-invaluable and for a small price, you get sooo much mana

Evolving Wilds and Terramorphic Expanse for that Bloodghast recur and basic land mana-fixing

Elvish Piper can cheat your fatties in play, but it's not the strongest creature ifself.

Black Sun's Zenith serves little to no purpose, other than being a board-wipe, I'd call it 'mezzo a mezzo'

You need a few more Mana Rocks, but not much

On the Landbase: 33 lands is unfortunately a little too little. If you came from other formats, then it's understandable, but generally, a minimum of 37 to 40 lands would be ideal. Trust me, I've had an EDH deck, where 1 (!) land was needed, before it rolled out like hell xD

I really like the idea of the deck / is my favorite color-combo :-)

I hope you could use some of the pointers - if not, that's cool - just trying to help

Good luck with the deck !
