PSA: Please do not abuse this as it is almost certainly a bug, I am just trying to make sure this is known so it can be fixed.
Note: This is not experienced by everyone so I will try to share as much info as possible.
The fireworks refresh when TH is closed and reopened via the TH chest pop-up button. This allows players to close any selection that they do not want without using any keys. This process can be repeated until a desired firework is displayed and then a key can be used to guarantee that firework's prize. I'm sure this is not intended as a player could guarantee 15 purple rarity prizes in 15 keys.
How I noticed: After my daily keys i noticed a purple reward so i redeemed a bond for keys. After redeeming the bond for keys I opened the TH interface via the pop-up (not thru extras menu) and the purple firework was not there anymore so I closed the interface. When I checked again there was yet another new selection of fireworks.
This should probably be fixed otherwise it will allow for heavy abuse of purple rarity rewards.
