The Design of Petty Wizards

Every card game lives or dies by one question: does each turn feel like it matters? In Petty Wizards, we wanted the answer to be yes — even when your hand is full of Mana cards and your opponents are one Grimoire away from winning.

The design of Petty Wizards started with a constraint: turns had to be short enough that losing never felt like waiting forever, but decisions had to be deep enough that you’d replay every turn in your head afterward wondering if you made the right call.

The Three-Action System

Many card games have a single “play one card” structure per turn, which makes each turn feel binary — either your card is good enough or it isn’t. We wanted more texture than that.

Three actions per turn was chosen specifically because it’s enough to do something meaningful but not so many that turns become analysis paralysis. With three actions, you’re constantly weighing tradeoffs: do I spend two actions on offense and one on defense? Do I develop my Grimoire collection today even though I could use this action to burn my rival’s Mana instead?

The Paralyze action card, which reduces your next turn to just one action, is devastating precisely because of this. Losing two-thirds of your agency for an entire turn is punishing enough to feel significant without being so crippling that you simply watch the game happen around you.

Why the Mana Shield Works the Way It Does

Early versions of Petty Wizards had a more traditional hit point system. You had health, spells reduced it, and when it hit zero, you died. It worked, but it felt sterile. There was no texture to being hurt — you were either at full health or you weren’t.

The Mana Shield changed everything. By tying your defensive resource directly to your hand management — sacrificing cards you might otherwise play — defense became a real decision. Every card you burn to shield yourself is a card you’re not using to attack, collect Grimoires, or hold as a potential instant.

We also made Mana Shield permanent rather than regenerating. Burn is burn. If someone drains your Mana Shield from 8 to 2 over two turns, you have to work actively to rebuild it, and every action spent doing so is an action not spent advancing your win condition. This creates a constant tension that keeps every turn meaningful.

The Grimoire Sacrifice Rule

This one surprised us during playtesting. When a player is overloaded with burn damage and can’t cover the overflow, they have to sacrifice Grimoires from their Play Area. The question was: where do they go?

The discard pile felt wrong. It was too permanent — losing a Grimoire you’d worked for would feel catastrophic, and players would often be eliminated well before the interesting endgame scenarios could develop.

Returning Grimoires to a random position in the deck was the right call, and it changes the dynamics of the game significantly. Eliminating a player doesn’t destroy their progress — it redistributes it. Their hard-won Grimoires cycle back into the deck for the survivors to fight over. An aggressive player who eliminates opponents early might find themselves facing a freshly stocked deck that their remaining rivals can draw from.

This also means the decision to sacrifice a Grimoire is painful but not final. You might draw it again. You might not. That uncertainty is exactly the kind of dramatic tension we were after.

Schools of Magic and the Dual Win Condition

Petty Wizards has two win conditions: collect two full Grimoire sets, or be the last wizard standing. This was a deliberate choice to support different playstyles.

Aggressive players can ignore Grimoires entirely and focus on burning opponents into elimination. Defensive players can turtle up, accumulate Grimoires, and try to win on collection before anyone can stop them. The tension between these two paths — and the fact that every player at the table has to watch for both — gives the game a lot of its strategic depth.

The five magic schools (Earth, Water, Fire, Air, Wild) each have different Grimoire set sizes, which means chasing different schools has different risk and reward profiles. Air has the largest set (requiring 4 Grimoires to complete), but the payoff of completing that set puts you most of the way to victory in one go. Earth’s set of 2 is fast to collect but requires completing both sets to win — meaning you still need another complete set afterward.

The Interrupt Window

Counterspell and Dispel Magic were added late in development, but they transformed the feel of the game. Before instants, casting a big spell was guaranteed to resolve. After instants, the possibility of interruption changed every interaction.

We implemented a five-second interrupt window when certain cards are played. It’s short enough that it doesn’t slow the game down, but long enough that attentive players can respond. Holding a Counterspell in hand is now a form of deterrence — opponents will think twice before targeting you if they suspect you might be holding one.

This layer of reactive play adds a lot of depth without a lot of complexity. You don’t need to understand all the intricacies of the interrupt system to enjoy Petty Wizards — but learning to play around it is one of the satisfying skills that separates intermediate players from beginners.

What’s Next

We’re continuing to iterate on card balance and AI difficulty. The expert AI in particular is something we’re proud of — it plays aggressively, conserves instants, and tracks the board state in ways that make it a genuine challenge even for experienced players.
