Theorycraft of Rise to the Occasion Paladin

Mulligan: Besides the quest, First Day of School is a must keep, not only providing the necessary minions to complete each step, but itself counts towards the quest. Knight of Anointment is also good for fetching Conviction (Rank 1), Hand of A'dal, and Blessing of Authority out of the deck.

Day at the Faire, Balloon Merchant, Stand Against Darkness, Lothraxion the Redeemed, and to a lesser extent Tour Guide, all serve to take Lightborn Cariel's reward and push it over the edge and close out the game.

While Animated Broomstick does count towards the quest, it's ultimately for turning Lord Barov, or the aforementioned post-quest Silver Hand board fills, into pseudo AoE. Likewise with Emerald Skytalon acting best in tandem with the buff spells.

Cornelius Roame helps dig through the deck since we're going to be playing a LOT of 1 cost cards, or help draw into the post-quest augments to finish.

Rustrot Viper is a predicted tech against Doomhammer or any of the profession tools, could easily slot in Venomous Scorpid instead.
