This is an evil, evil deck. Meant to control most metas, it also avoids controlling itself by having chars such as Hulk and Abomination. Destroyer is a better fit for hulk, and Red Skull for Abomination, this set up is just currently directed towards newer players.
Storm and Wanda are the big synergy here- Wanda is meant to go as X location is flooding- since usually people throw in many one costs when the flooding starts(Leaves two spaces for you to counter those one costs.). If Wanda isn't in your hand, Killmonger can handle any 1 costs they shove in there.
Elektra- Meant to kill any Nova or Nightcrawler early game, or possible spam cards in Gamma Lab.
Iron Fist- Meant to get cards in locations they cannot be played.(Sanctrum, Death's Doman, Luke's Bar, etc.)
Armor- Counter Destroy Decks.
Cosmo- Counter those annoying on reveal decks, also counters Destroy Decks and some movement Decks.
Killmonger- Counters Patriot-Blue Marvel-Kazar Decks,
Enchantress- Counters Iron man, Dino, and Onslaught Decks.
Professor X- Good for places such as Luke's bar, or Death's Domain. Easy win on those locations.
