I have also been playing elves for 10 years, and let me tell you, I know how to play the deck.
It is actually frustrating to lend the deck to a supposedly pro and seeing he can't figure out how to combo 2nd turn, or to do things I consider obvious, and I am sure that most people posting in this thread know perfectly well how to pull off the amazing techs this deck has, so that's exactly what I'm talking about, sure your list is great, I really think so it is a great list, but you can't just shout away that it is the MOST PERFECT list can find right now, ever, anywhere. Go make top8's a couple of them and then we'll talk, I have 2 top8 with my list from these last 2 month, and I only played 2 tournaments, and a friend of mine you ran the exact list placed 1st of out 61.
I am merely remarking your attitude. Help the community, don't just brag about being the best.
Spot removals, and UB merfolks really hurt us, but I tend to manage a way out about Merfolk, and it's also a big meta here.
The fall back plan just isn't good enough many times against Goblins, Zoo, or other aggro, because if we want to accomplish 7 mana for regal then we have to land elves, and that's when instead of Summoner's we draw Glimpse, with no elves in hand. Or when we keep all elves in hand and draw Summoner's instead of Glimpse, and then we waste one more turn against fast aggro which means death.
On the suggestions part, they were just that, suggestions, and I would only run Vexing Shusher out of all those cards, unless you also play
Chord of Calling, which grants some super secret ninja techs. Although it will be replaced by Sunith too probably, in my list.
Again, I do like your guys lists, but the difference is that I have tested all possibilities, yours, mine, others, and you seem reluctant to test something different.
