Active filters

Ondrej Psenicka is a deck creator best known for the Butterfly Playing Cards family, a marked deck project that has built a following within the card magic community. At The Joker House we gather his most popular editions, focusing on what really matters: how they handle and how the marking system works.

What you'll find in this brand

Ondrej Psenicka's catalogue in our shop revolves around the Butterfly line: marked decks in their colour editions (Blue, Red), currently in their 3rd edition, the themed Seasons versions (Fall, Winter) and the Gaff Pack add-on. It's a focused, niche catalogue aimed at magicians and enthusiasts rather than mass collectors.

The Butterfly marking system

What sets these decks apart is their marking system. The marks are integrated into the back design so that, once you learn to read them, you can identify value and suit of any card without obvious markings. It takes practice: the marks are discreet on purpose, so they don't catch the spectator's eye.

Build quality

Butterfly decks are printed on stock suited for magic handling, with a finish that helps dealing and fanning. The 3rd edition of the Blue and Red models is a revision of earlier versions, refining details of the marking and finish. The Seasons editions follow the same philosophy with a different aesthetic.

Gaff Pack: matching trick cards

The Butterfly Gaff Pack Black & Gold is a set of gaff cards (doubles, blanks, double-facers) designed to pair with the Butterfly decks. It isn't a full playable deck, but a set intended for specific routines.

Who it makes sense for

  • Magicians starting out or going deeper into marked decks.
  • Card magicians looking for a discreet, well-thought-out marking system.
  • Magic deck collectors interested in author-driven projects.

If you just want a nice deck for poker night, there are simpler options. If card magic interests you, Butterfly is a name worth knowing.

Frequently asked questions about Ondrej Psenicka

Are Butterfly decks easy to read?

They require some learning. The system is logical, but you need practice to read it fluently without it being noticeable.

What's the difference between Blue and Red 3rd Edition?

Mainly the back colour. The marking system and build quality are equivalent; it usually comes down to aesthetic preference.

Are the Seasons editions also marked?

Yes, the Fall and Winter versions keep the Butterfly marking system with a seasonal themed design.

Can the Gaff Pack be used on its own?

It isn't a complete 52-card deck, but a set of trick cards designed to complement Butterfly decks in magic routines.

Are they suitable for magic beginners?

They work well if you already know the basics of card magic. To start from scratch, it's better to get familiar with a standard deck first and then move to marked ones.
