I've had a decent winrate in top 200 masters with it. It's ideal for this time of the month where you can out-durdle everyone else in Masters.
There are quite a few combos, which occasionally don't line up when you need them - but with more practice you'll know to hold back a discard effect to turn on tribute when you need it, or to dump a weapon in the void to get a quick Sigvard out vs aggro.
Let me know if there are obvious improvements that I've overlooked.
