I usually enjoy playing characters who are quick and aggressive in games. In the first Slay the Spire, my favorite was The Silent – she could spread poison and throw a ton of daggers. But Slay the Spire II introduces some interesting new characters, and one that stands out is simply called The Regent.
Okay, so I’ve been playing The Regent, and at first, he seems absolutely broken. Seriously, tons of cards do huge damage and a lot of them cost zero! But there’s a twist. A lot of his cards don’t use regular energy – they need this special blue star energy. He starts with some on turn one, which is nice, but you’re responsible for making the rest, and that can be tricky. It’s a classic glass cannon situation – big damage output, but you need to manage your resources carefully.
Okay, so once you really learn how to play The Regent, he’s incredibly fun! I’ve been experimenting with him, and here are some of the cards I think are amazing to use with his kit.
10. Cosmic Indifference
Regal Ignorance FTW

Cosmic Indifference might not seem very strong at first. While creating 6 energy is useful, it’s usually more effective to draw fresh cards than to simply move a card from your discard pile to the top of your deck.
This feature is really useful because it allows you to keep and reuse important cards, like those that create extra star energy – those are often hard to come by. Also, many cards in The Regent’s deck have special effects when they’re played from the top of the deck, making Cosmic Indifference even more valuable.
To be honest, characters built to deal lots of damage but with low health really benefit from any extra protection. Plus, this card is great because it doesn’t require any special energy – it’s very affordable to play.
9. Furnace
Forging a Better Blade
Okay, so the Regent is already cool with his star energy, but his Sovereign Blade card is seriously neat. Basically, whenever I play a card that mentions ‘Forge’ anywhere on it, the Sovereign Blade shows up and just hangs out near his throne. The best part? It has ‘Retain,’ which means it doesn’t disappear after I play it! It sticks with me until I’m ready to spend 2 mana and actually use it. It’s like having a powerful card in reserve whenever I trigger it!
Furnace is a powerful card because it doesn’t just create the Sovereign Blade – it also makes it stronger with each turn! If you can keep it in play, the sword becomes a game-winning weapon. Plus, you can always use another card to recreate it if needed.
The Sovereign Blade is enjoyable to play, but doesn’t drastically alter the game on its own. However, when combined with Furnace, it becomes a really strong card, especially if you’re patient enough to build up to it.
8. Knockout Blow
One Punch King
Knockout Blow might not seem great at first. I generally don’t include cards that require a lot of energy – usually more than two – in my decks. However, it’s surprisingly strong because it offers a good trade-off, something I really appreciate based on my experience with the original game.
The Regent’s cards are unique because they often use star energy instead of mana. This lets you quickly build up energy – for example, by defeating an enemy with Knockout Blow – and then use that energy to power multiple attacks in a row.
It’s true, powering this takes a lot of energy. However, if you plan things around that, you’ll discover it’s actually quite useful.
7. Glow
So Shiny
Glow is a great card to connect The Regent’s regular energy cards with his powerful star cards. It doesn’t cost much to play, provides a little extra star energy, and also allows you to draw additional cards.
It might seem basic, but in card games, consistently gaining and restoring your resources is usually crucial for winning. That’s why you shouldn’t dismiss a card just because it doesn’t have a dramatic effect.
Using the latest version of Glow gives you a boost of star energy, making the game extra fun and powerful.
6. Black Hole
Get Sucked In
Because Powers stay in play during battles, Black Hole is a particularly strong card. It’s a low-cost way to increase the damage you deal to enemies.
What makes Black Hole so great is its ability to deal extra damage to all enemies, no matter how you’re using star energy. Because so many of The Regent’s cards focus on gaining or spending star energy, it’s quickly become one of my preferred cards.
It doesn’t deal massive damage right away, but it consistently wears enemies down. This makes it useful for handling groups of weaker foes, or gradually reducing the health of tougher bosses.
5. Particle Wall
The Perfect Shield
The Regent in Slay the Spire II is a high-damage, fragile character – a classic ‘glass cannon’. While he isn’t completely defenseless, focusing on building up star energy and dealing damage often leaves little room to prioritize protecting himself.
Particle Wall offers a solution if you have enough star energy. With just 2 star energy, you can activate it for a small defensive boost. However, if you have a large amount of star energy, Particle Wall will provide strong, lasting protection for an entire turn, constantly renewing itself until your turn ends.
I consistently performed better in games when my deck included Particle Wall. However, success isn’t just about defense – now let’s explore some powerful offensive cards.
4. Kingly Kick
Royal Rumpus
To be honest, my initial impression of Kingly Kick wasn’t great. It’s very expensive to use, so much so that I almost didn’t bother checking its power. However, I soon realized something important: the cost goes down each time you draw the card.
This means that by repeatedly playing and replaying Kingly Kick, you can eventually use it without spending any energy for the remainder of the battle. When used with cards like Cosmic Indifference, you can consistently draw it each turn.
In that context, Kingly Kick becomes one of the most potent weapons in The Regent’s royal arsenal.
3. Bombardment
Wish Upon a Falling Star
Bombardment is a powerful attack for The Regent. Although it has an initial cost, it continues to deal damage to your opponent each turn without further expense. This consistent damage can quickly weaken their defenses and overall strength.

Similar to Kingly Kick, the price isn’t the only thing to consider. Bombardment is a card I consistently include when attempting to climb the Spire.
2. Big Bang
Generating Resources
Big Bang is incredibly powerful. It doesn’t require any energy to use, but it generates energy, creates star energy, lets you draw a card, and can even create the Sovereign Blade.
The only real drawback to this fantastic card is that after you play Big Bang, it’s removed from your deck for the rest of the battle.
This card becomes truly valuable when paired with others that retrieve cards from your discard pile, or by enhancing its Big Bang ability. Having multiple copies is key, ensuring you can draw it when you need it most during challenging fights.
1. Stardust
Endgame Attack
The idea behind a ‘glass cannon’ attacker is to inflict massive damage while having very little defense. In the case of The Regent, Stardust perfectly embodies this concept.
This ability doesn’t require any energy to use, and instead powers attacks using your stored star energy – one unit of star energy per attack. I’ve often found myself with a surplus of over 10 star energy, allowing me to quickly defeat all enemies.
If you want to really get Stardust working for you, you’ve gotta build your deck around it. But trust me, once you get cards like Glow and Big Bang in play alongside it, you’ll be crushing even the toughest bosses and showing them who really rules – The Regent, of course! It’s amazing to watch.
