Awesome upgrade of Gagagigo, or further proof that I shouldn't make cards?

[Phantom Roxas]

Chaos Xyz: Gagagigo the Gallant
WATER Rank 5
[Reptile/Xyz/Effect]
4 Level 5 monsters
When this card is sent from the field to the Graveyard: Until your next turn, neither player may activate or Set Spell or Trap cards. If "Gagagigo the Risen" is attached to this card as an Xyz Material, this card gains this effect:
• When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can detach 1 Xyz Material from this card; inflict damage to your opponent equal to the Level or Rank of the destroyed monster x100.
ATK/3350 DEF/3000

Gagagigo Effect is really lackluster and makes me not really want this over Shark Drake, which is the same with a Limited Barian's Forced R4 into C105. Same advantage devoted but not even half the payoff. In this case, you pay even more for that effect and it's just... meh.

 

In this case, I get a 3350 that forces a pseudo-Cold Wave if it dies for any rank 4, including things like Black Corn. It seems worth the effort of running LBF to make it, when that card is kinda cloggy on its own. It gives me actual payoff and the Cold Wave doesn't last long enough to make a real issue. Solid card and seems totally fine for generic Rank Upping.

Attribute should be FIRE, just for more of the reference.
And with regards to what Black said- Burn damage could be increased.
