This Shuri pack is the kind of deal that would have me marching straight to the store for a Logans Loonies of i didnt have the hp on hand....
By that same logic, I could say that a 4* cover is worth 120 CP, which could be acquired with 17.14 stark buys which works out to 342,857 HP. That's a ridiculous number.
I think a slightly better method would be to note that the game lets you train a 5* character for 720 CP in place of using a cover, which is six times the 120 CP it costs to train a 4* character. The nominal value for a 4* cover seems to be 2500 HP: that's what it used to cost to train a 4* character in place of a cover, and seems a reasonable proportion of your standard H4H deals.
Multiply that by six, and a 5* cover is worth 15,000 HP.
@jamesh When I did a comparison between Thor's and Green Goblin costume bundles, I calculated that 50 CP is equivalent to 5000HP.So this bundle would cost at least 30,000 HP instead of 15,000.
