Okay, so a friend asked me and I had to say that I didn't know.
Ectoplasmer is active on the field. I offer my Ultimate Obedient Fiend as trib during my End Phase to finish them off. My opponent activated Pikeru's Circle of Enchantment when I summoned UOF.
Now Pikeru says that his effect lasts Until the endphase... so the thing here is that since Ecto can't be activated until the endphase, is Pikeru still active or not. I say yes because it lasts until the end of the end phase...but what is the truth?
