Currently 7-3 with this deck, although I have been hitting against a lot of Rakano aggro, so haven't been able to test it against powerful control decks (besides one feln control which it did win but could be anecdotal). Has a fairly good match up against other midrange decks, but this deck definitely has a tough time against endurance.
It is a fairly flexible deck that can be defensive or push really hard. Mulligans depend on if you have a 1 power removal or a 2 power removal. Most hands also need at least 3 sigils to be playable.
