Funkydiscogod, that's a great suggestion. To be honest, I cannot answer your question right now. On paper Disrupting Shoal seems like a great Arcane spell since I can theoretically stop everything I listed as a threat to Twiddle.

However, my main initial concern is stopping CMC 3 threats like Narset, Parter of Veils and more importantly Blood Moon . This would require me to sit on a Vizier of Tumbling Sands (There's about a 21% chance of having Shoal and Vizier on turn 3. I could run 4 Vizier and that would increase the probability to 26%). Not sure how I feel about these odds.

I'll give it a shot but I was already testing Flusterstorm as the go-to counter spell to protect the combo. As of now the results have been mixed as its great when trying to go off but doesn't do much to stop the multitude of threats that are played on the opponents turn. I'll let you know how it turns out. Thanks!
