"When this card destroys another monster as a result if battle, you can equip it to this card instead of sending it to the graveyard."
As for the rest, I think you could just give Kirby the monster's effect and stats. It'd make more sense imo. You can look at my version if you want [link] Otherwise, it's a good card. Except for the few OCG errors.
i like the idea of his effect, but the wording could use some work. it's very vague and confusing. had it been a real card, it'll start a lot of controversy XD and i think he's better as a WIND or LIGHT attribute ^^ overall, i like =]
