Reborn unlocks at Cunt Wars/Rank 15. At certain levels you can reborn your cards. Reborning resets them to level 1, but they start with a permanent bonus. Depending on the rarity of the card, it can be reborn several times. Common and rare cards can be reborn four times at levels 11, 16, 21 and 26 while epic and legendary cards can be reborn five times at levels 6, 11, 16, 21 and 26.
Total cost of Reborn
You can look at reborn as another way to level up your card. You have to include cost of leveling up your card back to the point of reborn. So the real cost of reborn depends on card rarity and reborn tier. Here are calculated costs of reborn for each rarity and tier.

Using reborn at higher level
When you use reborn 6 at higher level your card is still reset to level 1, but you get cards used to level up your card beyond level 6 back.
Example: you level up your Vampire to level 13 and then decide to reborn it. Now your Vampire is reset to level 1, gets reborn bonus, and you get back the 600 + 750 = 1350 cards you used to level up beyond lvl 11.
A bug may take place when you reborn cards involved with other soulbound to that: if the bonus that soulbind provides is gone, simply refresh the game for that bonus to show up again.
Example: you soulbind your Void Juggler to Evil's Helper for +3 ATK, then decide to reborn Evil's Helper. The +3 bonus on Void Juggler may temporarily disappear, but it will be properly displayed again after having refreshed the game.
