One of the decklist I have found while checking on the results of the recently concluded MagicFest (Grand Prix) Kyoto was a not-so pure Mono Red Aggro deck. That might be the appropriate term since there is a splash color of eight dual lands for Black. The only creature that can utilize this mana is the 2/2 Rakdos guy that gives you a late game gas: Rix Maadi Reveler.

I have played this dude on the purely Rakdos Aggro deck before and it can be very beneficial to refuel your hand after an aggressive start. The Spectacle cost is somewhat situational but for this Mono Red Aggro version, there is a lot of options or ways that can trigger it. Check out the deck list below. The deck was played by Teruya Kakumae and he finished in the Top 8 of the event.
