- This achievement involves more luck than most, as it requires several opponents being in the same vicinity at once, as well as being at an appropriate hp threshhold to all be dying to your hyper at once, which also relies on how many turns its been since you laid your trap.

In that scenario, cards like can be helpful for pinpoint maneuvering.
