You want to be putting down threats for your opponent to answer, not the other way around since your removal suit consists only of Blood of Air and, situationally, Third Wish. Fireblaze Obelysk, Portal Guardian, Dioltas and Tombstone + Second wish are all very threatening units that demand an answer. You lack any real card draw so keep that in mind before dumping your whole hand.
Aethermaster is really helpful since he makes sure you don’t clog up your hand with expensive minions or too many Scion’s wishes. Dig for Superior mirage when against Magmar, they are a very tough matchup for this deck without it and Aethermaster helps find that one copy rather reliably.
It is usually better to spread your buffs among multiple units instead of using them all on one. If you have no other good play it is acceptable to play a 6 mana Pantheran.
Other than that just try to develop as threatening of a board as you can. If you lose the board you will have a hard time coming back usually.
@alplod, that sounds very funny, I’ll definitely try a version with Duskdrinker for memes sometime
