I used this deck in this season (guardians of Galaxy) to reach infinite after the frustration of going from 98 to 89 using my Thanos Ongoing Zoo deck. This worked like a charm, got many 4 to 8 cube wins.
Just be aware of what cards you discarded during the match. Try to focus 2 locations .
Always snap when your win conditions are met
1 - Hela on hand with at least 2 good discards
Or
2 - jubilee pulled something really good into the field
Or
3 - Captain marvel is on the field or hand and there is any location hard to put cards.
If you don't have the key elements just retreat.
If jubilee pull hella is not a problem you can still discard and try to Odin on last turn.
On last turn there are cases when is better to use infinaut, happened to me twice when fighting in Cursed London? (The location that copy your card to another location).
So try to extract the maximum of your locations.
Is a pretty straight forward deck, you snap when you have the win conditions and retreat when not. High risk high reward.
Usually your opponent will have priority so don't be much afraid of Chang Chi.
