If I have a Luminous Energy attached to Alcremie, can I use its "Colorful Confection" attack to search my deck for any Energy type of Pokemon?
No, while Luminous Energy provides all types of Energy at the same time, it is not a Basic Energy card.

If I use Tinkaton's "Alloyed Hammer" attack with only one Luminous Energy attached, does it do 60 or 180 damage?
The Luminous Energy pays the {P} attack cost but also counts as all energy types including {M}, so you would do the bonus damage for a total of 180 damage.
