Question : Hot Event Carnaval Heroes 1

[Bakudankun]

Hi, i am really confused with this event..

It say i can SWAP heroes for 1diamonds only, if i recharge like 10-20K diams BUT :

Is it a only 1 choice event ? (not specified)
It i recharge 10k Diams, i can swap EVERY 10k Heroes for 1diams only, or i have to recharge 10k diams for Each ??
If i recharge 20k Diams, i can Get 1x 20K heroes prize + 1x 10K heroes prize for SWAP ? or only 1 of them ?

Why is the a second Carnival II event where its the SAME but you have to PAY in diamonds + Recharge instead of swapping ?? Because the SWAP is limited to 1 once again no info here :S.

Thanks a lot if someone can clarifie this.
I don't wanna waste diams if it lack of information...

You recharge the needed ammount and can swap 1 of the mounts . Since if you hover over swap/collect youll see it says total available swap times 1.

Well they tend not to announce it. But then again, we are the ones to double check what we buy, or swap
