Mulligans
General Mulligans
You should generally mulligan for 3-4-5 cost cards since you will get the higher cost cards later on anyways.
Mirror Entity is good because it makes your opponent nervous since he doesn't know what secret it is. If he decides to play a minion, well you know what happens. Piloted Shredder is really - even if it dies you still have a minion on board. Sludge Belcher is good for overall control.
This deck is made for the Tavern Brawl Clockwork Card Dealer. I don’t usually play mage unless it’s tavern brawl but I needed to complete some quests so I made this deck. Works really well against most decks (except hunter ofcourse). Enjoy
