ok here we go lets try

"The real question is if dragons can still breathe fire while under water!"

I thought this card matched with the most recent expansion because of all the new freeze mechanics. 

"After graduating from necrolyte training, his father gave him his first pack of Hearthstone cards as a reward. He took one look at the freshly-opened pack and then knew what he truly wanted."

Probably not my best; didn't have much time this week. It's the usual "Warlocks need health" style card. Friendly Bartender/Tournament Medic style design, but scaling to hand size and synergizing with the Warlock hero power. Very good Handlock card, probably good in some other decks as well. And for what it's worth, there is a real card that references Hearthstone existing within Hearthstone; Genzo, the Shark.

(EDIT: Added the flavor text.)

One man's corpse is another man's shoulder plates.

This one was kind of hard to design for, with common cards you aren't expecting a lot of complexity, you want a card that's flexible and fun, and I think Cadaver Collector brings just that. Just to note, his effect takes place wherever he is (Unlike Bolvar Fordragon, and it can stack higher and higher if more minions are killed while he is in play. This guy would fit in well in Zoo Decks as a late game powerhouse or would be a welcome addition to most Arena runs, where dropping this guy on turn 7 would most likely result in about an 8/8 or higher. 

FxxK You  Cobalt Scalebane and Drakonid Operative

If you combo it with Brann you can even kill the all X/12 legend dragon LOL

The effect is alike with Flametongue Totem.

But only the minion left side gains +2 attack, the minion right side gains +2 health instead.

Turn 7: Double Refreshing Elemental, Doppelgangster, Double Evolve, Opponent Concede

So this card is basically a 0-mana 3/3 Taunt but it can't be played without 7 full mana crystals. It isn't that strong because it can't be played early but has strons Evolve synergy. Also tagged as Elemental.

Balance: Compare to Nerubian Prophet. Nerubian Prophet has a little stronger stats but both cards are similar: You can play Prophet for free if you wait a few turns. Refreshing Elemental is free but you have to wait until turn 7 to be able to play it at all.
