Sell now.

Wouldn't it be nice to be able to sell all those 1*, 2*, maxed out covers BEFORE they pile up in the rewards bin. Or at least be able to "check off" 45 of the 50 rewards rather than selling them all one at a time. Sell all is nice unless you have some that you're holding on to until you have enough HP to buy a roster slot.

That would also cut down on accidental sells of needed covers.
