If you have 7 "Crystal Beast" cards with different names on the field or in your Graveyard: Special Summon 1 "Rainbow Dragon" or "Rainbow Dark Dragon" from your Deck or Graveyard, ignoring the Summoning conditions.
How to Get
Gives you an easier way to summon Rainbow Dragon by special summoning it from either the deck or graveyard.
Must have 7 differently named Crystal Beast monsters in the field and/or graveyard, otherwise this card does nothing.
Search Crystal Beasts
Use the cards to search Crystal Beast monsters out of your deck to quicken the activation condition of Rainbow Gravity.
These are the only Crystal Beast monsters and they also total only 7 different names, meaning that if you want to use Rainbow Gravity you would need to add at least one copy of each of these Crystal Beasts to your deck.
You could use That Grass Looks Greener in a 30 card deck to try and mill out all the necessary Crystal Beast monsters to fulfill Raibow Gravity's activation condition. To take this further you can use the skill Meet My Family to create a 38 card deck, milling more cards with That Grass Looks Greener.
Ignoring summoning condition just means you can revive a monster that normally cannot be revived.
However, ignoring summoning condition also means it is not a proper summon, therefore the monster must be properly summoned first (using the way written on the monster's text) before it can be revived.

I've tried this card multiple times and it doesn't work. Is it a bug ?
