Hooru's unseen mentored flying Valkyrie's

I think this deck could be quite viable, because it abuses the event rules very well - nearly all cards are discounted or cheap anyways.
There is this odd mix between Valkyrie + Unseen tribal, which revolves mostly around flying units + mentor. This could also be the time for Watcher of the Big Ones to finally shine.

Since there are 4 additional cards I chose to run 2 seek power even if the curve of this deck stops at 3 power (I added 3 monuments)!
