simple guide and some specific match mulligans 

the general idea of the deck is to draw into  the 7 mana spell as fast as possible  to reduce the cost of your win condition ''not your only out''  for dealing 40 dmg on 1 turn 

triggering mordresh fire eye can be done through using hero power and reckless apprentice 

you only want to draw minions  after playing  your 7 mana spell and thats why there are 2x arcane brilliance to maximize the chances of drawing  the spell asap 

survive until you draw the cards needed for the combo : discounted brann+mordresh and potion of illusion '' or if you drew him earlier and/or mordresh you still can play the combo without the discount from luna's pocket galaxy ..will go over that !!

incase you drew any of the 3 cards from the combo for the combo before luna's pocket galaxy you will want to play brann+ potion of illusion and when you draw mordresh after you triggered it  you play the 1 mana brann from the potion with mordresh for 20 dmg  but you have to bare in mind you will alter your approach to the game by trying to chip enemy health  more often so you can close the game 

mulligan

usually you will be looking to draw into the 7 mana spell as soon as you can 

if you have it in your hand you keep it  if not depending on your matchup

against aggro you  look for 1x wildfire/1xdoomsayer x1 arcane brilliance 

against combo/control : 1xarcane brilliance /1xstarscryer 

other than that you will keep looking for arcane brilliance in the early turns until you draw luna's pocket galaxy  and play it asap while addressing the board 

try to keep all card draw after you play luna's pocket galaxy 

usually the board control tools in this deck with the improved hero power will get you to drawing the combo and finish the game  

still testing the deck so far and its working .. not as consistent  and sometimes its clunky if drawing is bad 

will go into a more in depth guide but for now this should cover the basics
