He lies in wait at 11-2, with three Glaivezookas and a Highmane.

Gives Hunters access to cheap-ish removal in exchange for a short delay. There's the option of Garrison Commander/Beardo shenanigans if you like. (control hunter hype!) Your opponent can play around it by playing multiple small minions or killing off their big minions, but even so, there is value in blocking your opponent from playing big cards for a turn.

Hello, there is my participation (:

Class: Priest

Here is my entry xD

Card Name: Beckoner of Fel

Class: Warlock

Deck Archetype: C'Thun Lock/C'Thun Renolock

Explained:

 Flavour: "The whispers! Get out of my head! Lord Illidan has shown me the true way! Get OUUUTTTT!)

Don't let me catch you near 123 Fake St. again!

Flavor: When you can't win, you cheat...

Uh oh! Looks like its not only the Kabal, Jade Lotus, and Grimy Goons that are at each other's throats! Finja has a few other rival ninjas in town that would like to have a piece at him! 

Again this card is for obvious murloc synergy, as you effectively summon another murloc upon death. The thing is though, he'll make one heck of a disruptor for your opponent. Essentially cutting off their hero power until they summon your murloc, restoring their hero power. Pulls out your opponent's removal to save your other minions and an aggresive (obviously) body.

Also this follows all hero power rules. Once the hero power is used, your opponent's hero power will be able to use instantly, similarly to Sir Finley.

Let's make it simple. You can SMOrc your opponent while clearing enemy minion (or reducing it's health).

Tokens:  

For a legendary its pretty anti-climactic, sure, and there's no garuantee you'll even summon the right totem. That said, who wouldn't want to summon a chess piece? No one is who.

A Rogue weapon.

This card give power and value to your hero power use when you have a Beast. When you use it without a Beast it is just a 2 mana (card and hero power cost) deal 4 damage to the enemy hero (compare it with Mind Blast). With a Beast you not only deal 4 damage the enemy hero but also 4 damage to a random enemy minion for only 2 mana.

The double damage part make this card useful when you combine it with Justicar Trueheart. There is also a potential combo with Garrison Commander and Auctionmaster Beardo. Using this card twice in one turn also make your hero power gain quadruple damage. The potential to combo is there but with Hunter lack of draw will make it hard to pull off.

I hope you like my card.

Nice interaction with the druid Hero Power and cards such as Claw and Bite, that I think they need some love.

Edit - PD: You draw a card when attack is gained, not looking the amount of it. One Bite draws you a card. Activating Hero Power with Savage Combatant in play draws you two cards, because you gain attack two times: frist with Hero Power, second with the Inspire effect. Weapons are not effects that makes your hero gain attack.
