Training Grounds + Filigree Sages + Khalni Gem is nasty.
You could use Fabricate to help get most of this combo.

Mayael's Aria would could be nice in here

I'd use Howling Mine instead of / in addition to the Font of Mythos. Mines come out alot sooner than Mythos.

Now all you need to do is reduce the deck to 60 cards. The only thing I can suggest here is to reduce Eight and a Half tails to 3x or 2x because he's legendary. You could also take out / reduce some of the less effective creatures / spells

Very nice idea. I mite just make a similar deck.

Traitor's Roar works similarly to Backlash, but it's more expensive (mana wise), but can be conspired.

If you're putting enough lands into your graveyard, you could use Worm Harvest

Nice deck. 2 suggestions, 1- use Door of Destanies instead of Coat of Arms and 2- add Etherial Haze, it's another "Holy Day".

Looks interesting, but I suggest adding some mana acceleration (preferably creatures) other than Wild Cantor to help play the high casting cost creatures earlier.

It's a Liege deck. I've also made a strait green Liege deck, though it's different to this one.

Funny thing is I was going to make a similar deck using Earth Surge

Poison counters are fun, but I find you often kill the person with damage before you get 10 counters on him. People tend to get rid of the 'Poisonous 3' card before it does anything (in my experience) :-(

If you keep the shrines, Paradox Haze will be your best friend.

I also don't like the idea of having all 5 blades in a deck, but the challenge said all 5 had to be in.

And the combo is?

Looks like the same mana cards I use in my Dagonstorm deck. Take a look at "Crimson Whisps". It gives haste and lets you draw a card.

When I originally read the title I thought you'd be using Rite of Replication to make copies of the troll... I mite just try do that.

Verry nice deck. Even if you don't get what you need for your "combo", you could just attack with the troll.

Interesting build. I'd replace the Angel Song with Ethereal Haze, unless you want it for the cycling.

A nice black elf you should take a look at is Lys Alana Scarblade. The Wheel can help with the drawback of needing to discard an elf. Also take a look at Eyeblight's Ending and Pack's Disdain.
