It looks like a promising and strong deck. I'll give you some card ideas:
Madcap Skills +
Alpha Authority makes a Hexproof and Unblockeable combo that will win you a lot of games
Domri Rade gives you card advantage, clean the board and can turn even the weakest creatures you control into total slaughters.
Flesh //
Blood (the
Blood half) deals a lot of damage to your enemy.
Xenagos, the Reveler gives you mana, satyrs and the -6 is just great.
Fanatic of Xenagos you can have a 4/4 with trample on the battlefield for just 3 mana, or a 4/4 with haste until the end of turn (the +1+1 goes away too). People think that tribute is bad because your enemy can choose what is better for him, but the secret is: I'm okay with either choice.
Sakura-Tribe Elder works great, you can use him to block a creature in your opponents turn and then sacrifice him for a land.
Outland Colossus is my absolute favorite. In a perfect scenario, you would summon him, and the next turn you would have 6 mana. Then, you would add
Madcap Skills +
Alpha Authority and do 9 damage. After this, it will become a 15/12 that has Hexproof and CAN'T be blocked. And the best part is, you can finish off your opponent with
Flesh //
Blood and give a TON of damage!
Xenagos, The Reveler and
Sakura-Tribe Elder are here to help with the mana.
These are the strategies that i use on my deck, it maybe will work for you and maybe won't, but yeah, i hope i helped you
