Servine uses the attack "Wring Out" and flips heads against a Virizion EX with a single Grass Energy attached. It deals 30 damage, and the Grass Energy is discarded. Can the paralysis Special Condition be applied?
The Paralysis condition occurs within the attack text before discarding the energy. Since Virizion EX's Verdant Wind ability is still active the Paralysis is prevented, and then the energy is discarded.

If Sigilyph with the "Toolbox" Ability has Plasma Badge and Reversal Trigger attached, do I get to search my deck for a card when it is KO'd by an attack?
Yes, you can. The tools are still present on the Pokemon when it's KO'd (assuming the attack does not discard the tools first), so you would get to use the effect of Reversal Trigger since Plasma Badge makes Sigilyph a Plasma Pokemon.
