[Umbreon Dan]

a technician lead is possible, but the only reason to do so is because technician Giga Drain gurantees an OHKO on standard Swampert (while Energy Ball does not) so that absolutely must be on the set. However, without levitate, Stratagem will have extremely few opportunities to switch back in if it needs to go out, so technician is probably inferior. it could be mentioned in other options, or if there's support, it could be a separate set.
