This is a typical easy-to-build tempo deck, favoring Ongoing abilities to get value with Spectrum. Would love to hear any suggestions to improve further. :)
Spectrum - I chose her over America Chavez as she potentially has more value over the 6-10 by manipulating board states in all 3 locations rather than just add 10 power in one location. Same reason i play Spectrum over Onslaught, Odin or Hulk (a.k.a. the ones i have so far).
Jessica Jones - She takes Iron-Man's slot for me despite having no Ongoing synergy. The reason i picked Jessica Jones over Iron Man is that she can potentially hold a location all on her own, where she can becomes a 5-10. Iron Man is terrible on his own in a location, and may still be pretty bad if holding a location with weenies. Lots of games where she is the MVP, forcing suboptimal responses on turn 6, or just sealing a location on turn 5.
Colossus - I added him initially just to have another 2-drop with Ongoing ability, but proved to be invaluable when the dreaded Knowhere shows up. He straight up just secures that location on his own, and can be buffed by Spectrum if he faces another Colossus.
Quicksilver - This guarantees a turn-one play. Arguably something i need to replace, but i hate having to deal with turn-one guessing games with Rocket. Elektra seems like a good idea as she provides needed tempo by taking out an opponent's one-drop instead. Maybe one day when i get her.
Wolfsbane - still unsure which card to replace her with, which is why she is still in there. Very good synergy with Ant-Man which is a typical scenario having both of them in one location. Half of the time i play her along with 2 toons on a location, and i think a 3-5 is already decent value to gain tempo. May have to eventually replace with an Ongoing toon though.
Medusa - just a solid 2-4 tempo play on turn 2. I feel like her slot can easily be taken by another Ongoing toon, havent found the right one yet.
Nightcrawler - most of the time just a 1-2, but he has secured some games and even cause opponents to surrender with a well-timed Move to make way for a 3-7 Wolfsbane or a 3-6 Punisher. He also shines in locations where you cant "play" toons.
