I used 4 decks to get to infinite around collection level 600. So this is technically pool 2.5.
This deck git me many cubes from rank 60 to 95 when it started to drop in performance.
How to use the deck.
Turn 1
Play nova on middle lane (if possible)
Turn 2
Play whatever you have on hand on left or middle lane
Turn 3
Play Storm on the rightmost lane
Turn 4
Play Jessica Jones in the flooding area (that should ensure the lane in most cases)
Turn 5
If you didn't manage to pull Jessica Jones and need backup on Storm lane, you have Klaw and Vision that can ensure the lane later.
Turn 6
You have 3 options to consider
1 - Hulk - if you need raw power. Hulk is a powerful card with 12 points, most of the times calculate if you can win with it, most other 6 cost cards at that collection level are around 8~9 power and hulk can win.
2 - Killmonger - if playing against zoo decks.
3 - Enchantress - can destroy ongoing decks and even zoo if Kazaar and Blue Marvel are on the same lane.
