Mulligan Tips - Pirate Burn vs Aggro
The mulligan is pretty similar for all matchups. Always keep your 1 Drops, try to have a good curve and never keep spells. Only Keep GangPlank in the mirror. You win the aggro matchup by blocking as much damage as possible while maximizing your damage for the next attack.
