A lot of cards are marked essential. They kinda are.
Goal is to leverage both Angela and Kraven to hit their maximum potential, whiile still playing solid value cards elsewhere. The overlap of moving cards out of Angela's lane into Kraven's lane helps them both grow in power, as it frees up Angela for more procs while obviously procing Kraven's conditional.
Green Goblin is a strong card while also growing Angela, and some amount of the time, protecting both Angela (from Shang if we get her to 9 power, which we want to do) and Green Goblin (from Carnage/etc) with Armor can be valuable.
Polaris is an acceptable point value while also providing disruption via movement and activation on Kraven or Mojo.
Iron Fist ,Human Torch, and Cloak should be pretty obvious - do not be overly greedy on Cloak. He can also of course just help grow Angela. Note that Armor can also protect Human Torch from a Killmonger (esp if we grow him to 8 power). Also note I did not list Armor as core, as I've met disagreement thus far, so I am willing to accept that she isn't fully core...but I think she's an amazing card for a deck such as this one at the moment, as the meta also has a lot of Bucky/etc.
Finally for core, we really wanted to include Chavez to help with draw consistency, and this seems like a perfectly valid shell to rely on Dracula to get 9 power from the discard. There are drawback to this (if we draw more cards, etc), but we can reliably play our whole hand if we are not too greedy, as we are spending 6 mana on turn6 as well.
Suggestion cards are all untested but could earn a slot in the list (even over Drac/Chavez).
Deck name: reference to The Electric Slide (slide = movement?!), but Angela = Angelic.
