Radiant Greninja bug (2 water + other)

When energizing Radiant Greninja with two Water energy and one additional energy type, activating Moonlight Shuriken will trigger a choice for discarding energy. If the timer runs out without making a selection, the ability will default to discarding just one energy rather than two.

However, if Radiant Greninja is powered exclusively by Water energy, it won't provide the option to choose which energy to discard; instead, it will automatically remove two Water energy cards.
