mtg black dragon cards Necromaster [Dragons of Tarkir] the Blight Dragon gains haste until end of turn Subtype: Dragon, Colors: Black, Red,

They can either give a target creature +3/-3 until the end of the turn, flicker a nonland permanent, or create a 1/1 colorless Eldrazi Scion that can be sacrificed for one colorless mana

I also like the implications of having three of the four cards involved only matter for their type

How about copying BloodthirsterBloodthirster, or Dragonhawk, Fate's TempestDragonhawk, Fate's Tempest

Then discard two cards unless you discard an artifact card

It naturally ramps up in loyalty very fast, and it has a defensive ability to create a growing 2/2 Spirit token

These cards commonly interact with your opponents with at least one mode, though thats not a universal truth
