“Appropriate” may not be activated in the Damage Step.
In the event each player has an active “Appropriate”, if one player activates a card that allows him or her to Draw, an infinite Loop is created. If one player has all 5 pieces of Exodia in his or her hand during the resolution of this loop, that player immediately wins. Otherwise, the player who is unable to Draw first loses the duel.
If “Appropriate” has already been active when “Graceful Charity” resolves, the effect of “Appropriate” will successfully resolve. If “Appropriate” is not active when “Graceful Charity” resolves, “Appropriate” may not be activated.
