is valdris necessary or can I do without? Any replacement come to mind?

Valdris is not necessary at all. He is really good in some games and useless in others 

Nice deck

Have you considered Body Wrapper, i too have been loving and experimenting with questlock with kanre and sath, i was frustrated with being restricted to only cards below 9, and since i like twisted knowledge, it was even more frustrating. Thanks to Body Wrapper and Teron, i could safely cut expired merchant. Which allowed me to run Zephyr and Dragonqueen, but until this very moment, I was an idiot and didn't even think about the fact that unless you play both before you start your prime shenanigans, they become dead. So, thanks for that.

this deck is awesome very good idead 

but  do you will put in this deck alex dragonqueen and the normal alex ?

it is absolutely not needed. Kanrethad does more than dragonqueen and this deck will have duplicates of kanrethad in it no matter how you design the deck which disables dragonqueen. You also have plenty of heals so i don't see why normal alex? Burst? usually an uncleared Kanrethad board deals 20-25 damage killing the opponent

Thanks :)
