There are incredibly powerful cards in this deck, like Trazyn the Infinite which gains all activated abilities of artifacts in your graveyard when hes in play, and Biotransference, which turns all your creatures everywhere into artifacts, spreading the Necron influence across your deck
There are also a substantial number of Fiend monsters with a strikingly human-like appearance such as "EvilTwin" or some "Labrynth" monsters, either being a human who possess evil powers or a demon who takes a form of a human
All of the Main Deck monsters can be set face-down in your Spell/Trap Zone, and they are all about activating and subsequently playing during your opponents turn

And similarly my Shattergang Eldrazi deck certainly tries to win through combat, but only after throwing big haymaker creature spells
Some players will argue that cards like Fiery Confluence and Mystic Confluence are auto-includes in many EDH decks with those colors, and also staples of formats like Cube, but the others are playable in the right spots
