During the M12 release events I fell in love with the synergy between Onyx Mage and creatures that tap for direct damage. I wanted to see if I could build a casual deck around it and this is what I've come up with.

Using Onyx Mage and Virulent Swipe to turn your tap for one damage critters into a terror storm of creature removal. Using Disentomb to counter creature removal and Diabolic Tutor to get the cards you need, the goal is to get rid of anything your opponents can throw at you. Also included a few Doom Blades for those hairy situations when you're somehow faced down by a creature you can't snipe with army of tap for damage creatures. Best case scenario you've got an Onyx Mage and several tap for damage creatures with an Inferno Titan with deathtouch demolishing everything in your path.

I'm open to any suggestions for improvements and had a few cards that I'm on the fence about adding in the maybeboard. Another idea that could be utilized is to use the tap for damage creatures to bring out some beastly creatures with bloodthirst for a faster win con.

Enjoy!
