I guess I should have stated the very specific new situation. Will the copied dragon keep a deathrattle effect created by Dragonrider Talritha? You play Dragonrider Talritha, it dies and gives your, say, Brightwing a +3/+3 deathrattle. Then you play Brightwing then you copy it with Dragon Breeder. Does the copy keep the Dragonrider Talritha deathrattle? 

Does the copy keep buffs/deathrattles? I am guessing not.

Thanks for catching that! Yeah we only need 1 Slam.

This opens up a new archetype. Tempo dragon paladin. I think we are going to see dragon paladin with smaller low cost dragons that can ramp up and apply pressure.  

You guys! If I am reading this right, I think some of you are missing the mechanic here. If you have 6 on board and play the 7th you get Ra. Your turn is not over at that point, so now, how do we copy Ra a couple times in that same turn for the likely OTK?

I fell like Paladin, Rouge and Warrior are the only classes getting potential meta defining deck archetypes from this expansion. I am personally very excited for the Paladin secret cards, also bomb warrior and thief rouge look very promising. Everything else looks like filler to me. However, I am 100% sure that people smarter then I am will come up with some very cool new decks for the other classes from this expansion. Can't wait to cut and paste all their hard work!
