I had heard of ninja decks, but this looks like a ton of fun to play. Maybe one or two tricks of the trade would help. Gives +2/+0 and makes enchanted creature unblock able

First off, I would slim it down a bit. Cutting it back to 60 cards will up the likely hood of getting the goblin king by a good percentage. Then one drop goblins is where it's at, not three creatures with overwhelming force but 20 little dudes who do 2-3 damage each. Bright Ttone ritual, Goblin War Strike, Krenko, Mob Boss, and some sort of spell to where you can pay x to deal x damage.
Krenko will double your goblins, Goblin War Strike will deal damage to player for each goblin in play.
Bright Stone Ritual and Blaze make a really good combo.
I run one and will post it on my page here soon so feel free to check it out and my elf deck as well

Overall a nice looking deck. My brother rocks a knight deck that he put together himself. I'll put his up on my site here soon but I recommend trimming the fat on this. I'd reccomend making it strictly knights. Maybe some loxodon war hammers would help with gaining life.
And maybe something to keep those knight exemplars safe like whispersilk cloak

Jagged-Scar Archers for defense against flying, Maybe Eladamri, Lord of Leaves to protect your elves once they are out, and maybe you could look into some Wellwishers if you are looking for life. I also enjoy playing elves so feel free to check out the deck I've put together and pull any ideas from there.

Verdant Catacombs could go, instead you could put in a Terramorphic Expanse or Evolving Wilds. Maybe you don't need even a "Mana Bringer" anyways, you could always drop in a Wirewood Lodge or another Forest. No need to pay life for Mana.
