Questing For Two Card Design Competition

Priest and Mage both share an affinity for spellcasting and have both shown to have proficiency with spell-spamming. The Crystal Alcoves plays into this and encourages you to play several spells in a turn. Raxx the Risen similarly rewards you as you keep casting spells by building a board of 3/2 Crystals. If you're playing a bunch of spells, then you might as well get a good board out of it. :)

Lifesteal/Heal Concept of both classes.

'Always have a Totem to Hand.'

Warlock generally has an easier time discarding cards, but Mage has cards that explicitly discard spells such as Evocation and Submerged Spacerock. Warlock may have an easier time completing the quest, but Mage can more easily use the reward once it is complete.

The idea of this quest is that you could use it to create a control Rogue or Priest deck built around either spells or Deathrattles (or a mix of both), with Saria's Lifesteal effect providing the necessary stabilization to allow for the value and win conditions she generates to become relevant. Healing may seem out of place for Rogue, but the class has gotten Lifesteal effects before (mostly on weapons) and it is a dual-class card, so I don't think that this stretches the class's design identity too much. As for its effect on Priest, this quest would give the class access to N'Zoth, which should make Deathrattle Priest a consideration again. Yogg-Saron would also be very good in a spell-heavy Priest list, which the quest could also support.

"How much must I sacrifice?"

"Everything!!!"

"Nah, best I can do is 7 damaged minions"

"...deal"

Major support for decks that aim to stall during the early game with the help of secrets and use Deathrattle synergies as their win condition. Both themes are shared by Hunter and Rogue while a return of Sylvanas as one of the most iconic WoW characters in the form of a new card is long overdue.

Aww, she just wants to find some friends!

Both the Paladin and the Druid share the proficiency to go wide with their boards, so this should feel right at home for them. The flavor of the Hero Power suggests that the team gets better as they work together, just like a real raid group :)

Just for clarity, as a Druid you'd need to cast 3 Nature spells and 3 Arcane spells; and for Priest it would be 3 Holy spells and 3 Shadow spells.

The reward is one of the four Celestials, which is how the Wild Gods of Pandaria are called. In the case of Yu'lon, she is the embodiment of wisdom, spring, growth and youth, so an effect which grants passive Healing is very fitting for her.

This card would belong to a hypothetical Pandaria expansion, in which each class pairing would get a Quest with a Celestial as a reward (Warlock and DH would probably get a Sha or something)
