The Shrine Maiden!
The Shrine Maidens are the ceremonial protectors of sacred places of worships. They do not seek to fight, but will defend their people and honor their ancestors at any cost. Through their worship, they are able to convene with the dead, and know their way around many rituals that guide their prowess in fighting. Through tradition, they are masters of wielding flames, manipulating them to scorch foes as well as empower their allies aura.
Shrine Maidens have access to much card draw, but are not interested in playing fast. They deny their opponent's options with specific conditions and from there are able to benefit more from their symmetrical effects. The class supports both sides having a smaller board, with randomly applied buffs on their side, and punishes for wide boards on the enemy's side. With card draw and being able to play their pace, the class likes to set up scenarios for strong and flashy turns.
Some example cards:
Groundskeeper provides healing to both players keeping the game going. It also allows your discretion with the hero power to have some control on its ability.
Though your Hero Power grants your opponent options, cards like Fate's Edict deny their plays and can force sub-optimal plays. It also depends on your own play order, which could also allow for combo set ups.
Combustion is great burst, which is optimized by having a small board to mitigate the random effect. It works like Arcane Missiles, only instead of damaging enemies, it gives +1 Attack to your minions 10 times.
