Rainbow Energy and Energy Search (or Energy Ark) has its uses

Rainbow Energy
Pros:
- If you are using decks that have 3 or more types
- If your deck contains Darkness and Metal Pokémon (remember, you can only have 4 of each in a deck)
- If you are using a Southern Islands Mew deck
- Available in MMF (it is released as a Promo card, so you can use Rainbow Energy in a MMF deck)

Cons:
- Does 10 damage to the Pokémon you attach Rainbow Energy to
- Can't retreive it with normal cards such as Nightly Garbage Run and Energy Stadium; you have to depend on Energy Charge (all formats) and Recycle (Standard only), which needs a flip...

Energy Search
Pros:
- Helps you search your deck for Energy, making it pretty useful in decks that have 3 or more types
- Useful in some situations when card drawing is low and you have no Energy
- No coin flips, no self damage, etc.

Cons:
- Can only search for Basic Energy cards, meaning that you cannot get Darkness and Metal energy cards from your deck.
- Can be stopped by trainer and hand disruption cards
- Since it is in Fossil, and it hasn't been re-released in Legendary Collection, it isn't allowed in Modified or the Neo-On Modified.

If you weigh out the pros and cons, I would rather use Rainbow Energy. Rainbow Energy is a better card. It is much move versatile, can't be easily prevented, and helps you out more.
