Giant, maybe decrease the HP by 8% and damage by 7%

Hog Rider: Damage should just be decreased by 13% Hitpoints are annoying, so nerf them by 5%

Royal Giant: Perfect. That way I don't have to time my Inferno Tower.

Sparky: That will make her a totally new card. Just nerf her damage by 25% and that's it.

Rocket: YES YES YES YES YES

Three Musketeers: Keep the rarity at rare. Keep it at 9. And add Fireball to your deck. :P

I don't know what I would do with these changes.

TL;DR

Giant: Nerf is too strong

Hog Rider: Reduce life and Damage Nerf too strong

Royal Giant: Perfect

Sparky: Would be a new card.

Rocket: YES YES YES

Three Musketeers: Nah.
