I was so very disappointed when I saw the decklist for the Rakdos Event deck, so I decided to just make my own.
The star of this deck is, believe it or not,
Lightning Mauler
. Turn two Mauler into an unleashed turn three
Hellhole Flailer
is nothing to sniff at. Other shenanigans include the "rare" times that you have the right mana open after casting a Vexing Devil, them leaving it alive, then throwing down your Mauler to swing in for six.
My playtesting makes me think that swinging for a surprise six damage is something very common with this deck. The only decks I've had to test it against is a B/G Zombies deck and a Midrange Jund Ramp deck, but as long as I can get to at least three land this deck can wreck face.
That's not say it doesn't have its drawbacks: I do not own (nor do I intend to buy) enough Cavern of Souls to make the heavy creature-dependency of this deck anything more than threatening and my suite of removal comes down to some burn that is mostly only effective against other aggro/burn decks.
The sideboard is something I basically just threw together to pretend that I know what match-ups need what, but in all honesty, I'm flying blind in that department.
At any rate, that's my deck. Please leave me any feedback you have as to ways I can improve it, either in the sideboard or in the mainboard, and don't forget to upvote it if you like it!
