Scourge of Kher Ridges is sooooooo good. With enough mana you can blow up the board every turn.

My Mayael deck is pretty much just cheating fatties into play either using Mayael herself, Elvish Piper, or Quicksliver Amulet. I run a lot more fatties than most Mayael decks, just because I prefer to always hit a dude, when I activate her ability.

I also run quite a bit of mana ramp, which is very useful. Usually control decks can't handle me topdecking a fattie and then hardcasting it late in the game.

Also my play group is big on artifact/enchantments, so I like to run a bunch of 2-for-1 artifact/enchantment hate. I see you have return to dust. wear/tear and Hull Breach are really good. Hull breach is sorcery speed though. :/

I actually run blood moon in my deck, because most of my deck is basic with a couple fetches. The ramp package usually fixes my mana pretty well.

Vexing Shusher will win you games against control decks. One he resolves there isn't a whole lot they can do to you.

Good looking deck! I always like seeing Mayael do her thing! The name alone warrants alone +1.

I'd recommend Craterhoof Behemoth

Came for the title, stayed for the deck.

+1.
