Interesting wizards list. One guy in our local league played wizards for years, with a similar list. I never have had the guts to shelve something like this, despite I own everything but Vial (and I'd play stony silence over vial, and probably thalia too). In fact, the first deck I played in vintage was a UBW fish deck that some friend lent to me. I won two rounds thanks to kataki, barely understanding how to play my own cards.
Nowadays delveresque decks should be taken into account and any fish deck should have a good plan in the maindeck to answer them, via creature destruction or playing bigger creatures (mayor of avabruck maybe?). Nevertheless hate decks should be built with a very clear understanding of the metagame, and I still don't have a clear idea about what to expect in my local league. But I hope to see old faces in magic tables because of last changes

Yeah, it was Delver and friends that made me shelve Wizards! last time I played it. Trading 1 for 1 in that way isn't great, but it's doable. Omar Nieto was playing some radical looking Vial lists as well around that time and had Grim Lavamancers and Sowers. (

Thanks for reading!
