Summoner of Illusions special summons a fusion monsters who gets destroyed at the end of the turn. And Fiend Skull Dragon negates flip effects...
There was a ruling estabilishing that Fiend Skull Dragon isn't destroyed at the end of the turn if he was summoned by the effect of Summoner of Illusions, 'cause he negates that effect. But now:
1) That ruling no longer exists in card registry.
2) A ruling about Skill Drain and Summoner of Illusions says:
[Re: Skill Drain] "Skill Drain" will not affect lingering effects or conditions that are left over from a previous effect. For example, if you Special Summon a Fusion Monster with "Summoner of Illusions", and then "Skill Drain" is activated afterwards, the Fusion Monster is still destroyed in the End Phase. If you Special Summon a Fusion Monster with "Magical Scientist", and then "Skill Drain" is activated, the Fusion Monster cannot attack your opponent's Life Points directly, and is returned to the Fusion Deck at the end of the turn.
Looks like this situation is very similar to this one I'm considering, but we have Skill Drain instead of Fiend Skull Dragon, and the effect of Summoner of Illusions ISN'T NEGATED IN THIS SITUATION.
3) An effect cannot be activated during the resolution of another effect, for example a Jinzo flipped face-up by Ceasefire won't negate Ceasefire itself, so I believe Fiend Skull Dragon cannot negate the second part of the effect of Summoner of Illusion when he is summoned. And he cannot negate the same effect even later, like a Jinzo cannot negate a Waboku if it is activated before summoning Jinzo.
Considering all these, would actually Fiend Skull Dragon negate the destruction effect of Summoner of Illusions?
