This deck seeks to deploy cheap, well statted cards early and win the late game with the Ebony Blade, Giganto, or Magneto.
The Ebony Blade being ~essentially impossible to interact with makes it very difficult for opponents to counter, though Alioth still exists. The heavy presence of Killmonger also adds risk to playing out Black Knight before you have the combo (big card + discard) set up.
I chose Blade and Lady Sif for their consistency, which is even more important in a Black Knight deck. The silky smooth package is fairly interchangeable, but I would advise against adding too many high cost cards, as they hurt Blade's consistency.
This deck runs Magneto and Giganto over Infinaut due to their ability to be played without Ghost Rider/Black Knight. Magento is an especially devastating closer due to his disruption; Ms. Marvel, Shaw, and Darkhawk all play powerful 3-4 costs. Giganto's downside, while harsh, is not nearly as telegraphed as Infinaut's, and the presence of Silk and other movers in the deck makes Orka risky.
Shadow King as tech is especially useful against High Evo, Shaw, and Destroy; he can played on the final turn with Ghost Rider or the Ebony Blade for a massive point swing.

T2 -> Black Knight + Blade
