This is a red and white deck that is full of creatures that attack on the ground. There are a couple of fliers too. The point is to do damage fast to your opponent. The main ability is called "Mentor" where when attacking with multiple creatures a mentor creature with power greater than another creature can give that other creature a +1/+1 counter (permanently!).

In the next set, Ravnica Allegiance, this pairs well with:
Gruul (Red / Green)
Rakdos (Red / Green)
Orzhov (White / Black)
Azorious (White / Blue)
