While some of the cards in the Core Set are returning favorites from previous releases, it’s the brand-new and heavily modified cards that are catching everybody’s attention at the moment. These cards won’t just help form the foundation of Hearthstone‘s competitive meta in the coming years: they’ll offer entirely new strategies that could prove to be viable regardless of what other cards come and go through expansion rotations. There’s no shortage of noteworthy new Core Set cards, but here are some of the ones you’re definitely going to want to try for yourself.

Kor’vas Bloodthorn – Demon Hunter

Kor’Vas Bloodthorn checks all the major boxes for both Demon Hunter and powerful Hearthstone cards in general. With its low-cost, charge ability, and lifesteal functionality, this is one of those cards that’s simply “good” in nearly every situation.

Vanessa VanCleef – Rogue

First off, I love that card art. Second, and more importantly, Vanessa VanCleef’s ability is a fascinating concept that fits perfectly into the Rogue class as well as a variety of possible decks. What’s great about this card is the way that it forces your opponent to suddenly think about the order they play their turn in a way that they didn’t necessarily need to do before. Even if they deny you their “best” card, VanCleef has the potential to add enough value to your hand to make things very uncomfortable for them.

Aegwynn, the Guardian – Mage

This card may not look like much on the surface, but it honestly gives Mage players a few of the things that they’ve been missing out on due to the class’s spell-heavy Basic and Classic card sets. Aegwynn is a fairly stated card that greatly increases the value of minions in a Mage deck. It fits perfectly into the midrange plans of most slower Mage decks, and that Spell Power ability is going to be very handy for players looking to quickly end matches with a devastating barrage of spells.

Pursuit of Justice – Paladin

What makes Pursuit of Justice special (and potentially devastating) is the fact that it’s a low-cost spell with an effect that lasts you throughout the remainder of the match.

Crimson Clergy – Priest

While recent Hearthstone expansions have done a better job of giving Priests effective early game cards, the class is always searching for a new one-drop that better lets them set the pace for the rest of the match. Crimson Clergy could be that card. It’s going to be interesting to see how many times players are able to actually utilize this card’s effect in an average match, but even if Clergy dies fairly soon after it’s played, it still forces opposing classes to play off their back foot in a way that they rarely had to worry about when facing Priests.

Novice Zapper – Shaman

I’m not sure if Novice Zapper has the support it needs to really thrive at the moment, but as a standalone card, this new addition to the Shaman library certainly has nightmare fuel potential. Aggressive Shaman players will certainly benefit from what this card offers, but Novice Zapper’s stats and abilities mean that it has the potential to really shift the momentum of a match in several common scenarios.

Lord Jaraxxus – Warlock

Lord Jaraxxus may not look “new” on the surface, but a closer look reveals that the card no longer sets your health to “15.” Instead, you gain 5 armor on top of whatever health you already have.

Bloodsail Deckhand – Warrior

Like the best fantasy villains, Pirate Warrior is one of those deck types that is always threatening to come back and set the world ablaze. When it does return, Bloodsail Deckhand is going to be a big contributor to the archetype. Even as a standalone card, this one might offer the right combination of tempo and value to make it worthy of inclusion consideration for any Warrior players running a least a couple of weapons in their deck.

Taelan Fordring – Neutral

Here’s another card that doesn’t initially seem to pass the eye test. Hearthstone history has taught us that more expensive cards with low stats have to bring something pretty special to the table in order to see play. However, I think Fordring offers something special. That “Taunt/Divine Shield” combo is traditionally pretty valuable (even at this cost) against aggressive decks, and the ability to draw the highest-cost minion from your hand is one of those triggers that can either be used for combos or simply to transition into the late game a little more effectively.

Ysera the Dreamer – Neutral

While some of Hearthstone‘s re-designed Dragon Legendaries are either seemingly worse than their former designs or need to be played with a little more before rendering a verdict, Ysera feels like a strict improvement in the ways that matter most.
