Forum:"You can only use this effect..." question

Hello I've got a pretty simple question here but I was checking some card effects and I read an end text that I never really thought too much on till now, the end text that reads: "This effect can only be used once while this card is face-up on the field."

In particular I was seeing this with the newly revealed OCG monster Schuberta the Melodious Maestra and it got me thinking if I summoned another of her and used her effect already would the new one I then summon be able to use it's effect as well and even in the same turn?

Also, if I flipped one facedown and flipped it up in the same turn I imagine this would reset for that one in this case right?--Eternumblaze (talk • contribs) 03:18, January 30, 2015 (UTC)
