SENTINEL IN THIS DECK IS THE GOAT, dont sleep on him. The fact that you can always have a cheap proactive play is so big in this deck, if you play it enough you will understand me.
Also Chavez is the biggest bait on tech decks.
Other tech Options:
–Enchantress , this deck doesn't play any big turn 6 units so she could help you achieve that and gather info on what the opponent will do
-I could be wrong, but I have been playing with Storm lately, and I think Scarlet witch is better than her. This deck lacks units like Vision, Nightcrawler or Klaw to be able to fight the flood location. You could try to run Vision as another 5 drop, but I'm not sure.
– Iceman for more early game plays, the only problem is that Killmonger is antisynergistic.
If you dont have Lizard you can also play Captain America, Iceman or Punisher instead. I have ran Punisher with success in the past.
-Killmonger is 99% times a turn 6 play, use him wisely.
