All cards can be reborn to get bonuses.
Cards can be reborn 4 times if they are Common or Rare and 5 times if they are Epic or Legendary.
To rebirth a card, it must be a certain level, which is higher for each subsequent rebirth (see table below).
If a card is reborn above it's rebirth level (e. g. first rebirth of a level 12 rare card) you get back the cards that were spent to get the card above the rebirth level.
There are events that, after rebirth, return a percentage (usually 10%) of the cards spent getting the card to rebirth level.
The table below shows the level for rebirth for each rarity of card:
|Rarity||Rebirth 1||Rebirth 2||Rebirth 3||Rebirth 4||Rebirth 5|
|Common||Level 11||Level 16||Level 21||Level 26||-|
|Rare||Level 11||Level 16||Level 21||Level 26||-|
|Epic||Level 6||Level 11||Level 16||Level 21||Level 26|
|Legendary||Level 6||Level 11||Level 16||Level 21||Level 26|
