Actually, I find most don't know that this stays on the field, even after the Sword is gone, and this includes people who have been playing for over a year. It doesn't say that it goes away, so it stays.

Also, you can have as many cards set on your field as you like. There is no limit. If you have more than one in hand, you can activate them all in one phase, as there is also no limit to the number of times you can activate an impact in a turn, provided the conditions are met.

And as for reusing it. Right now, there isn't, but the boosting effect still applies while it is set even after the Sword is used. However, in the very next set (which is a special all foil set that has only monsters and has every world in it), there is a card called Agent Ninja, Mamiya that might as well give your Formation another round of use. Heck, you can even now have more than one Sword in a Formation, in which case, you can activate either when it is appropriate to do so. Hope all this helped!
