This deck is pretty self-explanatory...You're playing Big-Hand Dino but this is a bit different, in that, you aren't utilizing the usual 4-drops in Moon Girl/White Queen...
You are playing all the S.H.E.I.L.D. cards (Agent 13, Maria Hill, Agent Coulson and Nick Fury) to fill your hand with random cards, buffing Devil Dinosaur in the process...sometimes these cards will be super handy, sometimes they are just cards in your hand.
Quinjet is obviously crazy good in Dino decks, since most of the cards in your deck fill your hand with cards from outside the main deck.
The mainboard doesn't really run the usual 4-drops as mentioned, but Rescue is just a big 4-drop but even Rescue hopefully plays a off 4-drop to whomever you get from Agent Coulson, which again would have its cost reduced by Quinjet.
Nick Fury or Taskmaster plays as the decks 6 drops, your either filling your hand for dino, or playing basically a second Dino...
*Honorary Mentions*
ANY of the standard Dino cards that aren't in this build, you already know what they are, so I won't type them.
Wave/Magik - This is mostly as a sub to get Magik on 4, Dino on 5, Fury on 6 and hope the your 3 6-drops are worth the 2 spaces in your deck to wasted on this combo hahaha...keeping in mind that those 6-drops now cost 5 and on turn 7 with Quinjet, so you can play basically a 6-drop and a 3-drop which is nice...
But that's the fundamentals of this build, let me know what you think!
