Senior Game Designer at Wizards of the Coast. Former ML Engineer at Pinterest, Ph.D. in TCS. Ask me about designing Magic Cards! Or my monored cube! Or math! Or board games!https://bsky.app/profile/bsweitz123.bsky.socialhttps://bsky.app/profile/bsweitz123.bsky.social/post/3mikxwfscps2gThis might be my favorite card in all of SOS. I love every part of it: the art is amazing, the flavor text is badass, and the design gives a high floor while forcing you to figure out what cards to play with it to maximize its abilities.03 Apr 2026 05:20 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mikxwfscps2ghttps://bsky.app/profile/bsweitz123.bsky.social/post/3miktxj5bgs2zExperiencing spoiler season as a Magic Designer is really weird because I’ve seen all these cards before but I kinda forgot how cool they were so I still get hyped. Anyway I love SOS and I hope y’all will too!03 Apr 2026 04:09 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3miktxj5bgs2zhttps://bsky.app/profile/bsweitz123.bsky.social/post/3mhrurn557c2fI built another model. It’s a marble maze and it was frickin hard. My fingers are so sore from pinching and pushing wood but it feels great to be done and it’s cool af.

Proud to say that I’ll be attending the first Riftbound Regional! It was a harrowing day since I started with a loss but won out. Leaving with a Q and a metal card makes a nice weekend :)02 Mar 2026 02:17 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mg26rluxgk2whttps://bsky.app/profile/bsweitz123.bsky.social/post/3mfy72rcjxs2rDay 2 the Vegas RQ at 6-2! Really love my deck construction, though there is a lot of seal hate out in force. Game is completely impossible to play at 100%, just going to aim for about 95% and play at a reasonable pace.01 Mar 2026 07:16 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mfy72rcjxs2rhttps://bsky.app/profile/bsweitz123.bsky.social/post/3mfvnjgrxkc2cWent 6-0 at the pre-RQ tournament at Vegas. Sadly the Ahri metal cards were out but I got to at least got to pick up a heavy version of my legend.

Wasn’t meant to be. But I’m happy to have made a deep run with a self-made brew. Jeweled Colossus is the truth, just some nice chonk for the pump spells.

I've had my Brion deck for 15+ years. I was super happy the ECL set team asked me to design a new member of the Stoutarm family. Bre is great in my Brion deck, but with her own buildaround power for any new fans. #wotcstaff06 Jan 2026 06:34 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mbqdilerg225https://bsky.app/profile/bsweitz123.bsky.social/post/3mbknzyepls2pJust updated my cube overviews to be a little more sales pitchy for the next CubeCon. Now that I've played in one, I understand the mechanics of how people choose the cubes to play (it is quite an overwhelming process). And advertising that I'm #wotcstaff probably doesn't hurt :)04 Jan 2026 00:26 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mbknzyepls2phttps://bsky.app/profile/bsweitz123.bsky.social/post/3mbdw3rfpxs2d2025 was an incredible year for me and has brought me a lot of happiness. I met my wonderful girlfriend, I saw the successful release of several work projects I put a lot of effort into, and I found a new card game to compete in. Really excited for 2026!01 Jan 2026 08:02 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mbdw3rfpxs2dhttps://bsky.app/profile/bsweitz123.bsky.social/post/3mbcuscnyds2qMy favorite card of the year is Teval, arbiter of virtue. The text never changed in from my brain to print, just the mana cost and power toughness. I think it’s super fun, you can get big pop off turns but it’s risky and you’re often balanced on a knife’s edge. The art is also incredible. #wotcstaff [contains quote post or other embedded content]31 Dec 2025 22:06 +0000at://did:plc:hqrgrpub2dik5d3w244foekh/app.bsky.feed.post/3mbcuscnyds2qhttps://bsky.app/profile/bsweitz123.bsky.social/post/3mb5q4o5bvk2dNew upgrades to the monored cube!

Been trying to add cards to laser-focus buff some strategies and it seems to have worked. Combo cube has also improved after cutting half the under supported stuff to properly support the other half.
