Hello, I know that the following is a question discussed about several times already, but I would like to understand the exact effect of the card in question. In many discussion forums is repeated that, generally, the "untap" is valid on a creature already '"untapped". I think that this clearly violates the rule 701.17 (b). What 's the right way to play the card? And above all, why the rule citated above does not apply?
Thank you.
