To stay alive against Toggwaggle's insane early tempo, you need lots of cheap clears. Thankfully, Wild Priest has lots of them.

To stay alive in the early game, all of these spells come in useful:

• Silence - for the scary deathrattles
• Renew - to keep you alive, and to cheaply advance the quest
• Spirit Lash - very effective for keeping you alive in the early turns
• Breath of the Infinite - they'll play lots of low health minions
• Mass Dispel - essential against all the deathrattles as wall as the Escaped Manasaber
• Shadow Word: Horror: clears most of their board and none of yours

Because of this flurry of spells (Renew is a real star here), Grave Horror becomes playable very quickly. These can easily win the game for you, not just because of their high health; Toggwaggle will smash his face into them repeatedly, and the 7 attack will make the job of wearing down his health surprisingly easy! 

Now go build that wall and make Toggwaggle pay for it!
