Please comment down below if you have some ideas for Dokkans/Rebirths, and I'll see what I can do to make a suitable example.

Here's my first Rebirth idea for a struggling card, Entrusted Mission Super Saiyan 2 Gohan (Teen).

Name: Bearer of Potential Super Saiyan 2 Gohan (Teen)

Cost: 42

Leader Skill: All Types HP and ATK +30%

Super Attack: (Comet Punch) Huge ATK boost, supreme damage to opponent

Passive Skill: (For the Future) All allies' Ki +2, ATK +20%

Links: Super Saiyan, Saiyan Warrior Race, The Saiyan Lineage, Golden Warrior, Prepared for Battle, Shocking Speed, Shattering the Limit

Ki Meter: 2;9;1

HP: 8402

ATK: 8054

DEF: 4356

And I guess for the picture it could look something like this:

(Minus the extra stuff and with Gohan more centered and detailed)
