Eh. I like the design, but the card leaves something to desire. It's definitely better than SS Chichi, as a Main personality, but the original Chi-Chi has a great power in a Goku or Gohan deck. We'll have to see if she combines with Goten beyond her card power (which if modified will be 2 beef attacks), other than that, my current rating stands as follows. 

Rating : 1.5 in both formats

Yay! It's Chi-Chi, the most dreadful character on DBZ, even more dreadful than Frieza :p

Standard: This card is pretty good, anyone who has it puts it in their ally deck, especially if they have Goten in play (even if he isn't out yet..) 3 stages may seem feeble, but if you beat down your opponent enough in a combat and then perform this attack with say, Blue Assistance drill, and Heroe's Battle Ground it'll do 7 life cards of damage ^_^

Rating: 2.3

TE: Allies aren't seen as much here, and Chi-Chi decks aren't often played. So it gets a bit lower a rating
