Mulligans
Beginners control warlock list for fighting aggressive opponents on ladder.
VS Aggro
Play minions on curve and fight for the board
VS Control
Life tap aggressively and find Lord Jaraxxus as soon as possible
VS Mirror
Hard mulligan for Lord Jaraxxus most control list will be running Tickatus so play more aggressive with minions and play Jaraxxus first.
Acidic Swamp Ooze Ogremancer are decent tech cards in this meta Ysera the Dreamer is our extra value, but can be replaced for any legendary of your choice.
Good luck have fun
