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.
Kiseitai (R Weevil Farm/Ranked Ticket) can be used against LDs where you need no backrow using Draw Sense: Spell/Trap. If you can consistently activate the skill, 1x copy of Barrier/Sanctuary is enough and frees your deck for more Cloudians and a better Draw Engine of Monstercards like Thunder Dragon, Crystal Seer. You can add Sangan, Gokipon, Danipon or Rai-Mei to search your Ladybug.
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...
