When Fire Princess is face-up on your field, the once per turn healing of Golden Ladybug would also become once per turn burning your opponent for 500 LP. This multiplies with the number of Golden Ladybugs in your hand.
Aromage is an archetype of monsters that activate their effects and benefit from healing LP. Golden Ladybug can be useful as a sure trigger for their effects every turn.
Although it sounds like a dumb question, the OP has a point.
Normally the page will tell you where to get the card, but it doesn't mention it.
If you found this page by clicking a farming guide, you won't know which box it came from.
It seems that it could work well with Ra. This Ladybug can be searched by Gokipon, also it increases your LP for Ra, and you could use it with Worm Bait and Double Summon for Ra. Now we only need some consistent way to draw Ra...
