General Mulligans
Duskbreaker is a keep regardless of the opponent. Same with the Cleric. If first draw gets me the Pyromancer against aggro I'll keep that, or Lady in White against slower decks for a guaranteed strong end-game.
Most wins are not the OTK but those cards are clutch when needed. Highest I’ve reached is rank 14.
Against aggro: board wipes all day. Duskbreaker, Wild Pyromancer, Primordial Drake and Shadowreaper Anduin.
Against control: Cobalt Scalebane will get targeted for removal, which is great to clear the way for our even bigger minions later on. Usually save Mass Dispel until you have lethal. Ideally Shadow Visions can be used to assemble Divine Spirit and Inner Fire, then hope you can get a Wyrmguard to stick (sometimes better without a dragon in hand). Save the OTK combo until you actually have lethal!!! Can’t stress that enough (looking at you, Frost Lich Jaina)
Against mid range: With Extra Arms and Cobalt Scalebane you can go face, unless there are good trades to be made. Save that Shadow Word: Death for The Lich King that seemingly most decks run, or against an early Mountain Giant if you can’t stall it with taunt.
Against combo: Card draw will help us assemble our combo first, so make sure the Cleric doesn’t go to waste. Psychic Scream is better than removal against Warlock because of Bloodreaver Gul'dan.
Against deathrattle/buffs/mechs: Swap out Wyrmguard and Ysera for Silence/another Mass Dispel.
