If I use Victini-EX's "Turbo Energize" attack but choose to attach the two Basic Energy cards from my deck to Sigilyph with "Safeguard", what happens?
Sigiliph is a valid target for the choice of Benched Pokemon, but since Safeguard prevents all effects of attacks done by Pokemon-EX the energies would be discarded rather than attached to Sigilyph.
