Kazar buffs Ant-Man, Elektra, Squirrel Girl and her Squirrels, Sunspot, and Nightcrawler. Use Armor to protect your 1-costs from Killmonger, and use Cosmo to block On Reveal chains with Wong and/or Odin. Try to get Angela and Bishop down early to gain control of the field. Ideally, your turns will look something like this:
1: Sunspot if you have him, or any other 1 cost
2: Angela/Sunspot, or other 1 cost(s)
3: Bishop/Armor/Cosmo. Bishop is preferable, but if you can tell your opponent is running a destroy deck Armor can block a Killmonger, and if you see an On Reveal chain being set up Cosmo can shut it down early.
4: Kazar
5: Cosmo/Armor for control or Blue Marvel/Captain America for buffs
6: Blue Marvel/Kazar if they haven't been played yet, anything else if they have
Don't worry about leaving leftover energy to get a good setup, as Sunspot will get buffed from it so long as you have him put down. If you aren't facing Pool 3 decks, Cosmo can be swapped out for Wolfsbane or another 1 cost if you prefer. All of the 1 costs are replaceable, but I highly recommend Sunspot and Squirrel Girl for this archetype. Armor can also be swapped out for another 1-cost, but I prefer having the control. Onslaught can also be used to double Kazar and Blue Marvel's buffs. Captain America and Nightcrawler can also be swapped out, but Nightcrawler provides good coverage for locations like Sanctum Sanctorum or Death's Domain. Debrii can be swapped in as well, as the rocks she creates receive Kazar's buff.
