[Crisys]

RBW Master 62 cards, 0 sideboard 3 {Isolated Chapel} 3 {Godless Shrine} 4 {Blood Crypt} 3 {Clifftop Retreat} 3 {Sacred Foundry} 2 {Rogue's Passage} 4 {Dragonskull Summit} 22 lands 2 {Master of Cruelties} 2 {Crypt Ghast} 4 {Lightning Mauler} 2 {Sire of Insanity} 4 {Nearheath Pilgrim} 4 {Boros Reckoner} 4 {Typhoid Rats} 4 {Rakdos Cackler} 26 creatures 3 {Rakdos's Return} 3 {Searing Spear} 4 {Pillar of Flame} 4 {Boros Charm} 14 other spells Sideboard

I haven't had a chance to check this deck out yet, it's just an idea in my head.  Thoughts/criticism?

I like master or cruelties as a secondary, the infinite life combo with reckoner would be nice to proc, crypt ghast ramp into rakdos, idk seems like a decent idea to me on paper

For any given deck that has one or more cards in it, one single card is always the worst. The lowest amount of cards that we are allowed to put in a constructed standard deck is 60. This means that two of the worst cards in the deck can be eliminated, to make your draws/openig hands better and more consistent. I think that the two {Crypt Ghast}s you have need to go, because you have so few swamps in the deck. It's almost like a 2/2 vanilla for 4. I could be wrong though. Test it! If you find that you are almost never happy to see a certain card, or find that it has extremely narrow applications, cut it and continue to test.

I like your idea, I would not really expect {Master of Cruelties} in it. It's a nasty surprise for your opponent. One minute they have 7 lands on the battlefield and a {Sphinx's Revelation} in hand. Now they reluctantly throw their hand away! Infinite life is also cool.
