Hey Mark! I'm wondering, why do you allow yourself to reprint color-breaking cards? It gives players, especially newer players, the wrong idea about the color pie. Instead of reprinting Chaos Warp, why not either (A) print a different, non-breaking card that achieves whatever it is Chaos Warp achieves for red, or (B) change the color pie so Chaos Warp isn't a break?

The problem is players want access to the cards. The compromise was to not add them to formats that they aren’t legal in. That’s why color pie breaks won’t get reprinted in premier sets (not counting bonus sheets that don’t change card legality).

How would you fix Beast Within and Chaos Warp?

Not print them.

Why isn't Tibalt's Trickery a break if Chaos Warp is? I agree Warp is a break, but isn't Trickery just that effect, changing one thing into another, but affecting a spell on the stack vs. permanent in play? IMO Trickery is a break, red shouldn't keep a spell/effect from happening, just change how it happens, but even if it was allowed it still has the same issue as Warp, it answers enchantments and doesn't replace what it countered with something of the same type the way modern Warp effects do.

Changing a spell is a different thing than destroying a permanent. For example, blue can change spells, but can’t destroy permanents.

"Because digital has become such a big part of Magic, we’re always conscious of misclicks." That sounds like they should add and 'are you sure' to digital instead of removing options for paper. Some of us have played paper for 20-30 years and will never touch digital, it's not exactly fair to us. Using polymorph effects on your own stuff (like Chaos Warp) isn't exactly a corner case, it's super common. Same with other effects that may be harder for digital but make sense to be able to do.

When we make Magic cards we have to think about all the ways they’ll be used by various players and balance those needs accordingly. For example, we’ve adjusted our templates, so they always work in multiplayer even though the majority of Magic play is two-player. That’s part of what being part of a robust game entails, players understanding that how other people enjoy the game can have impacts on how they play.

High five to whoever got Foglio to do art for Chaos Warp in 2X2. He is my favorite MtG artist by far!

High fives to be applied.

Seems like you're getting a bevy of white counterspell questions so I have one, but I have a recent example! Tibalts Trickery. I get it is flavorfully more like a chaos warp, but it literally says "counter target spell." That implies that red can fully counter any kind of spell (with potential upside) and white cannot. Even if that was a one-off, it sets an odd example for "who gets counterspells."

Tibalt’s Trickery shouldn’t have used the words “counter target spell” for the very confusion you bring up. It’s also why we moved permanent transformation, as done through creature tokens, out of blue as putting the words “destroy target creature” just threw people. Red can’t counter spells. It can transform them into a different random spell.

To bring up red answers to high toughness creatures: Red can prevent creatures from being able to block, destroy defenders, temporarily take control of and then sacrifice creatures, and chaos warp creatures. White didn't have any good alternatives to card draw, so I think it makes sense that wizards would focus on that more.

They are very different issues, and you are correct that red had a lot more ways to work around its weakness.

Is the chance for Chaos Warp to "miss" (reveal a non-permanent) a bend or a break (or neither)?

It’s a break for any permanent red can’t destroy.

So if Chaos Warp was "Shuffle target non-enchantment permanent into its owner's library..." that would be okay

Yes. It would be even better if it turned the permanents into permanents of the same type.

Can Red get an unconditional counterspell that doesn't replace what it counters (ala Chaos Warp)? Or is Red Elemental Blast now considered a break?

Red Elemental Blast was considered a break when I started at Wizards in 1995.
