Mulligans
General Mulligans
These are the cards you never keep in your starting hand. Always mulligan these away. Always.
Aggro Mulligans
If you know or suspect that your opponent is playing aggro always mulligan Chittering Tunneler. Wrathguard is also a card you want to mull away for obvious reasons.
Be aggressive while inflicting damage to yourself to unlock the incredible potential of cards like Hooked Reaver.
