If the Senshi are pulling out a new attack every other episode, it sounds like on the tv show side, they're playing with special effects because it's fun. It sucks from a continuity perspective, because now we gotta find a reason for it.
How about if what they really have is a kind of internal energy pool, like an Iczer? The energy pool can be used for anything they can think of, but it has to be *focussed*. The concept, their mental image of what the power does, is extremely important, because that image is what determines what the power does.
In that case, the full attack sequence would be the Senshi focussing their concentration on what they wanted to happen. The gestures, the words... None of them are really *necessary*, but they use them because they're a kind of psychological crutch. Also perhaps because it's cool.
To a bunch of 15-19 year old girls, posturing and yelling out attack names and posing dramatically would be irresistable. But it might not actually be *necessary* for the power to work.
