RB Demon Midrange Budget (Modern)

Early game:

• Control your opponent's board and hand with Distress/Duress and removal spells.
• Chumpblock higher threats with Gifted Aetherborn and Augur of Skulls, trying to get board and card advantage for the mid game.

Mid game:

• Gain more advantage and overwhelm the opponent.
• Desecration Demon is a god creature in putting pressure because of flying, low cost and high stats. If he becomes tapped it's only a good thing: your opponent has to sac to avoid life loss. It works extremely well with Archfiend of Depravity, so aggro can't overwhelm you and tokens can't be effective at all. This sinergy is also useful against other midrange decks. Remember to Fling him if threathened, important against control decks with lots of removals.
• Master of Cruelties can be a finisher if the board is already under your control or a godly chumpblocker that doesn't die in combat to anything. In the worst case scenario, he will get a removal spell, saving your other demons. In the best case, you can Fling him after the combat to win the game.
• Bloodgift Demon is a support that can win you games. Works extremely well in conjuction with Toil//Trouble and the -8 ability from Ob Nixilis to damage the opponent at will, or it can gift you even more card advantage. He's nice also as a finisher to close Master of Cruelties' job.
• Liliana Vess can help you developing your strategy (searching for the demon you need at the right time can win you games), stressing the opponents (playing with no cards in hand against you is a ez game and ggwp you did your job well). The -8 means that, after you wiped the opponent sacrificing your demons, they can come back more with other friends. No deck can cotrnol the situation if that happens, and this means game over 98% of the time (if they don't have Damnation in hand, obviously).

Late game:
-This is the case in which you have already won or lose.
If you are against control and you don't have already gained great advantage against the opponent, you probably have lose the game. But if you have Rakdos's Return you can come back anytime. In those situations it can win you the game alone.
If you are against aggro in this phase, and you played well, you shouldn't be able to lose. Your creatures are too bulky and BIG to be threatened by any brainless horde.
If the game is stalled, you can try to close it out with Lavaclaw Reaches, really useful in these situations. In general, it's preferable not to reach turn 10-11 with this deck against more lategame threats such as Planeswalkers or unbeatable creatures (Wurmcoil Engine, Eldrazis, Titans, etc); playing this deck well means that you should win by turn 6-7-8, attacking with big creatures an harmless and surrendering opponent.

Conclusions:
This is a really versatile deck, but try to use a proactive game plan instead of a reactive one. You're a midrange, not a control! You can't beat a deck designed to work in a certain manner using its same method. If it happens it means that your deck is overpowered and the game was unbalanced from the start. Same thing for aggro decks: you can't overwhelm an aggro playing aggro! Just follow your strategy and you'll eventually win.
Just try to not be behind in control early because it can excalate quickly and badly.
It's a deck designed 4fun and for 4fun matchups, not competitive ones. It surely can work with some changes (Ob Nixilis for a non-budget Liliana, Olivia Voldaren for Master of Cruelties, more Archfiend of Depravity and Bloodgift Demons or Demigods of Revenge instead of Desecration Demon...). The budget will surely change but it's your choice. I created this deck to only have fun seeing other people and friends tilt as I play my favourite, most versatile and funniest cards.
Hope you like it at least half as I do.
