This is one of my favorite decks and my first decent one. Comment with suggestions or advice. If you like it +1 it.
This deck is a Aggro-Control deck based around Master of Cruelties, at the start of the game you batter your opponents creatures and start to get out your Heavy creatures. Then you pull out your Master of Cruelties and make it unblock able with Rogue's Passage. And that's basically the game. I tend to win by turn 9 maybe 10. I've noticed that it just frustrates the hell out of people so I would try to get in their head. If you can't think straight you can't make the right moves.
Cards like Shock and Magma Jet are used at the beginning of the game to get rid of creatures and frustrate your opponent. At this time I would usually play Thoughtseize but depends on what lands you have and what other burn cards are in your hand.
Then you through out either Chandra's Phoenix or Satyr Firedancer. You use Chandra's Phoenix to keep a constant deal of damage to your opponent. Using Satyr Firedancer allows you to keep his creatures at bay and lets you prepare for your more heavy beasts.
You could through Mogis, God of Slaughter in buy this point to take out more creature or do a constant flow of damage but you might not need to just for the fact that you could get your heavy hitters out. Really your choice when to throw him in. If I have seven or more lands I would use
Rouge's Passage
on him constantly because seven damage every turn is a monster.
Next comes your heavy hitting flyers like Desecration Demon and Rakdos, Lord of Riots. This again makes opponents creatures utterly useless. Your opponent might use their burn spells on your creatures making it easier for your Master of Cruelties to survive.
You could through Mogis, God of Slaughter in buy this point to take out more creature or do a constant flow of damage but you might not need to really your choice when to throw him in.
Once a Master of Cruelties is out
Rouge's Passage
will do the rest this can put your opponents to one and let you burn them or attack them with a creature next turn.
Anger of the Gods is in there for a backup card if everything is failing. Just use this to clear the board and start to just burn the hell out of you opponents.
Slaughter Games is in there to take out pesky creatures that will chose havoc in numbers.
I a few burn spells that I can trade out for in the sideboard which is ultimately your opinion to trade and swap. Slaughter games is in there to play against only against certain decks but really it is your choice what to trade and swap out.
Change and edit the deck however you like and come back to me with the new one. It would really help if I could get some feedback so I can build some better decks.
