Flashy Cards Exchange

[casseopeya]

Hope someone can answer this about me quickly,
I am trying to exchange this for Ace Hearts etc in Hot Events (See Attachment), does it need to be ace heart to exchange for ace heart? That'd be weird... I have 4 flash cards in total.

Can someone explain me how to get Ace Hearts otherwise? (if it's from other chests only?) ?

First, are you trying to trade these for Flashy Ace of Hearts? It's a trade where you use Flashy Ace of hearts for those items (300x seraph's stones, Ace of spades and ace of hearts).

Note that Flashy and usual cards are different...
Then, are you sure you own flashy ace of hearts? I see you mentioned you have 4 flashy cards, but which ones?

As for where to get Ace's of hearts hot events are nice for it:

can anyone give me some advice how to get 4 flashy ace of spades and 4 flashy ace of hearts in 1 HOC event?
