That One MEMEY Deck Everyone Secretly Wants

The title pretty much says it all.
However, I wonder if anyhow I could add some consistency when fighting the boss.
So far, 6 wins consistently in gauntlet, but kinda wrecked on the 7th aka the boss.

Any constructive advice is appreciated, thanks :D!

PS: That Whispering Wind is surprisingly effective, you just discard a 5 cost card, and boom! Thunderstrike Dragon.
