Mulligans
General Mulligans
Early interaction, card advantage that doesn't reduce your Barnes allotment, Barnes because sometimes he just makes everything else crazy (or, at least, instantly increases your board), and Rexxar helps provide additional choices no matter the matchup.
Aggro Mulligans
Early interaction, life gain, and hellacious disruption to anyone who isn't beefy all in minion based aggro.
Midrange Mulligans
Slow the game down, interact, and sometimes just Barnes for brilliance.
Combo Mulligans
Look, Combo is always an awful matchup if you're not sure what they're playing. Your solution is just play your game as well as possible and try to disrupt if at all possible.Control Mulligans
When your opponent is drawing cards and approaching fatigue quicker than you, you are asking questions and creating from a pool of powerful minions.
Don’t let your memes be dreams, unless they’re off Ysera.
