It's all about looking for Dark Pharaoh Tekahn while controlling the field safely. Cobalt Spellkin will probably farm couple more Dragon's Hoard, especially when paired w/ Spirit of the Shark. But Spellkin might be unplayable because of her fairly high cost, so always play the Spirit at turn 4 and Spellkin at 5th if you have chance. Frizz Kindleroost can be a solution for this, but not recommended if you don't use more dragons like Evasive Wyrm.(Yeah we're talking about a lot of good cards.) Good thing is that Rogue's other one-mana spells are decent, and great for opening Combo.
Once you've acquired Tekahn, the game will go fairly easier. Rogue has like dozens of ways to have lackeys, and even more when using Galakrond-invoking deck. Because of that, 4/4 lackeys are too nice to have.
Other than all that, even if you fail to find Tekahn, you'll probably have bunch of good stuff if you're lucky. Zentimo is very nice to have and delete enemy minions with cards like Walk the Plank, Sap, Eviscerate, et cetera.
Thank you for reading, and hope all these were understandable, since English isn't my first language. Here's the replay of that screenshot.
"Created by Dragon's Hoard"
Flik Skyshiv also did a great job taking down two 11/14 Onyxia's.
Well how I play this deck is simple; but first of all, Galakrond, the Nightmare, two Dragon's Hoard and two Cobalt Spellkin plays important role in this deck. Put more Weaponized Piñata or a Brightwing in the deck if you want.
