Congrats for your impressive run! Unfortunately, the meta looks more like Legacy than Vintage, so it's difficult to adapt it to a meta filled with Noble Fish, Drain Decks and workshops :p
Do you have any report, in order to make an idea about how to play the deck properly? Thanks!
Thanks

If I where to play this in powered metagame (say BoM IV or in the USA) I would play the same maindeck but with a different sideboard.

I don't have a tournamentreport yet sorry (whenever I try to write I make a play mistake right after).
The MPV's are Vial and Pridemage. Epochrasite (!?) and Grunt with Clamp are also pretty good. No one expects Epochrasite
If I where to cut any cards it would be Bolt/Helix... (but I won't do that)
