If I attach a Grass Energy to Skiploom with the "Solar Evolution" Ability but there are already 4 Jumpluff either in play or in the discard pile, can I still search my deck for that Pokemon and fail?
You cannot use Solar Evolution to search your deck since it is public knowledge that you won't find any Jumpluff if all four copies of the card are in known areas.

When you attach "Rainbow Energy" from your hand to Skiploom with the "Solar Evolution" Ability, do you place the damage counter onto it before or after evolving to Jumpluff?
The owner of Skiploom can choose the order of the effects. They can choose to place the damage counter from Rainbow Energy before evolving; however, if they choose to use Solar Evolution first the effect of Rainbow Energy is ignored because Jumpluff is not the same Pokemon the energy was attached to.
