Black: Control / Discard / Damage = Win (Modern)

The general strategy of a midrange deck like this is to control the opponent in the first turns (I call it phase 1). This deck uses black control and discard to do that.
Later in the game these kind of decks are building up their win condition (I call it phase 2). I decided to do that as combination of token and other damage dealers.

The phases are described in detail in separate chapter below. At this time I just like to explain the main target.

Turn overview (how it should work):
T1: I start with a discard spell in turn one. If possible with the option to see the full hand of the opponent.

T2: Next step is to react on played opponent creatures if they are harmful. Otherwise bring out a Waste Not if possible. Normally I can handle one creature and get it rid off the next turn. So having a trigger option for discarding in turn 3 is worth it.
Another option is to play Nezumi Shortfang if opponent deck is slowed a bit or keep the pressure going on with next discard.
In worth cases I have to save mana to react on next opponents turn creature drop to destroy it on board.

T3: React on opponents turn 2 or let him discard (with waste not trigger)OR play Nyxathid to create some pressure.

T4: Bringing out win condition. The rest is playing down the opponent and win! hopefully ;)
