Each nonland permanent that doesn't have Fading or Vanishing gains Fading N, where N is that card's converted mana cost.
That does not work properly because of the following rules.
702.31a Fading is a keyword that represents two abilities. "Fading N" means "This permanent enters the battlefield with N fade counters on it" and "At the beginning of your upkeep, remove a fade counter from this permanent. If you can't, sacrifice the permanent."
614.1c Effects that read "[This permanent] enters the battlefield with . . . ," "As [this permanent] enters the battlefield . . . ," or "[This permanent] enters the battlefield as . . . " are replacement effects.
614.12. Some replacement effects modify how a permanent enters the battlefield. (See rules 614.1c-d.) Such effects may come from the permanent itself if they affect only that permanent (as opposed to a general subset of permanents that includes it). They may also come from other sources. To determine which replacement effects apply and how they apply, check the characteristics of the permanent as it would exist on the battlefield, taking into account replacement effects that have already modified how it enters the battlefield (see rule 616.1), continuous effects generated by the resolution of spells or abilities that changed the permanent's characteristics on the stack (see rule 400.7a), and continuous effects from the permanent's own static abilities, but ignoring continuous effects from any other source that would affect it. [emphasis added]
An alternative that does work properly is "Each nonland permanent that doesn't have Fading or Vanishing enters the battlefield with a number of fade counters equal to its converted mana cost and has Fading 0."
My score against #5 should be 3. If I go first, starting from turn 3 I cast Serene Remembrance targeting nothing to make sure that it won't be discarded. If my opponent casts Wistful Thinking, I cast Serene Remembrance targeting all the discarded cards on the next turn. I eventually cast Entreat the Angels to get five 4/4 Angel tokens and attack with them the next turn to win. Shrieking Affliction won't hit me more than a few times.
