This is a simple, but very flexible card that should see play in different kinds of Priest decks. Dealing 3 damage for 2 mana is good enough to be played in an aggressive Shadow deck since it goes face and provides more reach. The added flexibility of offering a heal could be nice in aggressive mirrors too.
For Control Priest, it’s a removal card that can also heal. Cards that only heal usually aren’t good, but cards that heal while also providing other utilities tend to see play, even if their healing output isn’t the greatest. A 6 health heal for 2 mana is worse than Flash Heal, but Flash Heal can’t kill an early game minion. Torrent can, which means it’s far less likely to be a dead card in your hand. There’s always something out there to take off the board.
This card seems flashy and tempting. Kvaldir’s effect can be stored for a future turn, so there’s no need to combo it with another card immediately. Kvaldir’s issue appears when you start looking for potential synergies in the current card pool. There just aren’t very good ones. The best card to pair with it is Flash Heal, but do we start running Flash Heal just for the purpose of using it with Kvaldir? In addition, Kvaldir can be quite awkward to use in a deck that runs effects like Holy Nova and Cannibalize.
Kvaldir can’t really work in a Shadow deck either since all the healing spells tend to come from the Holy spell school. This is a minion that seems to suggest that synergy is coming in a future set, but we don’t see it right now. For example, this card would be fantastic to use with Circle of Healing. Add this type of card, and Kvaldir becomes more likely to see play.
Varia could be the spice that Undead Priest needed to come back to the meta in greater numbers. Varia doesn’t offer a lot of threat through her stats, but as a 5-health 3-cost minion, she’s quite difficult to remove on curve. What’s more is that she is almost impossible to ignore. If you remove the Priest’s undead minions without killing Varia first, you take a lot of damage and give your opponent free value. If you develop a board to contest the Priest’s advance, they can simply trade into your board while pushing a lot of damage to your face and reload their hand.
In that way, Varia is very similar to Putricide. A threat that can easily generate a lot of value upon entrance, but game winning if it’s allowed to snowball. Varia is undead herself, so Undying Allies can give her reborn while Basaleph can resurrect her. It’s not going to be easy to get rid of her.
Seems like a staple for Undead Priest and might become one of its most dangerous cards.
Final Thoughts: Shadow Priest got freshened up and may attract more interest thanks to Varia. Control Priest is less likely to use these cards, but perhaps the archetype adds a Kvaldir burst package with Torrent, Flash Heal, Grace of the Highfather? Might be fun to try, at least. Otherwise, it’s just Yogg.
