what do you think about my 3 teams? could they survive against the new speedsters?

Inhumans
75 GOTG015 Triton
75 GOTG026 Crystal
75 GOTG027 Gorgon
75 GOTG028 Karnak
150 GOTG036 Black Bolt
75 GOTG037 Lockjaw
75 GOTG038 Maximus (with 2 alpha primitives on the side)
75 GOTG039 Medusa
675 (i think about fortitude on black bolt, but i'm not sure)

Heroes for Hire
85 DP009 Misty Knight
100 DP011 Silver Sable
69 DP030 Paladin
115 DP031 Elektra
100 DP032 Punisher
85 CA006 Black Widow
80 FI007 Iron Fist
56 ATA085 Heroes for Hire (7x)
690 (what would be the best add for 10 points?)

Guardians of the Galaxy
55 GOTG001 Gamora
100 GOTG002 Drax the Destroyer
56 GOTG003 Mantis
110 GOTG030 Star-Lord
100 GOTG051 Groot
80 GOTG052 Rocket Raccoon
150 GOTG055E Iron Man
28 ATA011 Guardians of the Galaxy (7x)
679 (what would be the best add for 21 points?)

the Guardians-Team won very easy against mole-man, giganto and 5 moloids.
heroes for hire was a very lucky win against an evil inhumans-team with maximus, unspoken, maelstrom and 4 alpha primitives.

Guardians. All the way. Throw a Book of the Skull in there. Because why not. or a Battery.

i really hate resources. i just put shellhead on drax and nanobots on mantis.

I'd go with the Inhumans, adding Brilliant Tactician to Maximus and a Terrigen Crystal object (700 points, even).

People may hate me for this post but this is my favorite team for high minimums of figures would have to be

FI 104 Odin at 350
FI 101 Loki at 30
And x
FI 002 Asgard trolls
Where x= your remaining points after split lip and full book of skulls. For higher point games you can throw other beaters like Thor or tanarus
