STAGE ONE: Protect and Invoke. 

Try to protect yourself through the early game whilst starting to build Galakrond and simultaneously completing Corrupt the Waters..
Don't be afraid to upgrade your minions early with Bogstrok Clacker however you'll need to keep one charge of your Boggspine Knuckles for stage Three.

STAGE TWO: Prepare for Battle.

By turn 6-8 you will have hopefully depleted some of your foe's resources whilst you continue to protect yourself with Dragon's Pack and Shield of Galakrond
Once you complete your quest and have fully upgraded Galakrond you need to equip Boggspine Knuckles ready for turn 10.

STAGE THREE: Wage War.

Using your new hero power to trigger Galakrond's mighty army twice you now have four 8/8 minions with Rush which you can also upgrade.
