I am only glad that there it is possible to build a pirate tribal in Ixalan :) Although tribal was the most obvious draft build in Ixalan I think the most powerful build for draft in the set is U/W control with all the cheap white removals and disables the set has to offer. But I am really happy about drafting Dominaria soon, I checked some of the upcoming style and I like what it has to offer!
Thanks :D
