I was stressed making this deck, I don't think I built anything super amazing, but I guess that's what being in bronze is all about.
My winning condition was Tidecaller, and it won me 3 of my games by itself by milling the opponent's entire deck. Otherwise it was mostly surviving. Bouncing back creatures, quandrix charm counterspells, etc. Everything milled 3 cards.
If it died I brought it back with Emeritus. Arcane Omens seemed a bit weak here, but when Is aw that it could mill 10 cards (along with a mana cost 5+ divergent equation) then I was full on survival mode.
I did get lucky and played other decks that were about using a lot of removal or such. Against really aggro decks I would have lost (which is what one of my loss comes from). Second loss happened against someone who was on their final turn (I had emptied their deck) but topdecked the final card needed to overrun me.
