Pursuit - Allow
Assuming that the opponent is not using Zapdos, when Voodoom is switched in, it is likely that most people would try to switch in to a different pokemon to try to take it out. Pursuit with STAB would catch runners, leaving them damaged for Togekiss to be able to beat if Voodoom should be taken out. It's a good synergy move, which was the point of CaP 11.
