As my 4F mask was well-received, I thought I'd swing by with another mask brew. Hasn't treated me terribly in high master's, has a plan, and can execute it fairly consistently if it doesn't die to hard aegis aggro. Feel free to mix up your interaction suite (3 anni/2 rindra's/2 banish/4 hailstorm/2 feeding time) as you see fit.
Beyond that, same old plan. Play mask, gain life, draw cards, remove some units, slam tormentor or devoted theurges of unusual size, attack, win.
