Useful, I suppose. At least in
Focused, there is not alot of speed removal for setups, and the
current strong decks (Orange Ally), uses alot of setups, so this
can be a helpful sweeper. The fact that it is a rather big
energy, and not an event, is nice as well, as it cannot be
sphered like some of this set's other mass removal cards. Worth
the one slot it will get in Focused, though probably not 3, if
you are running it's style.
It's probably a little helpful in
Expanded, as ball decks tend to have a huge load of setups
(mainly DBall search and combat enders), and wiping them all
from the board in one swipe is never bad. In this case, it is
worthwhile to run as many of this as you can, though in the
Sensei deck, methinks.
Average in Limited. Setups can
help, but they are not game-breakers, either. It still shoots
to the dome, though.
