Hi Mark. I have a particular fondness for creatures with the stats 1/4 and the ability Flying. These creatures have always been in the Esper colors. That's why the Selesnya-colored "Congregation Gryff" stung my Magic heart. To me, this is a design flaw. Why is this creature partly green?

I don’t think white/blue/black has a lock on ¼ fliers. No color or sets of colors should have a lock on a combination of stats and abilities.

Will Homarids eventually get the same treatment as Cephalids getting their creature type updated to Lobster, or are there too few of them to warrant that change? We did just get one in OTJ with Deepmuck Desperado. I always associate Cephalids and Homarids so I wonder why one is getting an update and not the other.

I do think Homarids will eventually get changed. To Crab is my best guess.

Do coloured artifacts being common make a return to Alara, and Esper by extension, more difficult because coloured artifacts were Esper's identity?

Esper is as much about all its creatures being artifact creatures.

Hi Mark! I really wanted to say I really like the appearance of people from throughout the multiverse in the set, including non legendaries like Djinn of Fool's Fall ( a Tarkir Djinn), Congregation Gryff (an Innistrad Gryff), Deepmuck Desperado (Homarid from Dominaria), Gold Rush (which shows an elf from Capenna) etc... This is exactly the type of things I wanted to see with the Omenpaths! I hope we get more cameos like this in future Omenpath centric sets :)

How do others feel about it?

So far Temur, Bant, Esper, Naya and Grixis have been previewed. Can we expect all 10 three-colour combinations in OTJ ?

No, all ten are not there.

Dakkon Blackblade is definitely a color pie break, right? Right?!?

It’s a green ability on a white/blue/black card. : )

Is there a reason that multicoloured mana symbols aren't used in mana sources? I.e, instead of "Add [B] or [G]", it could be add [B/G]?It could probably save a bunch of card space, especially in 5 colour mana sources, if 5 colour multiple type pops were added, i.e. "Add one mana of any colour" vs "Add [W/U/B/R/G]"
Though, I suspect a 5 colour one might not work in formats like commander, since then it would count as 5 colour identity card

The reason is it implies things that aren’t inherently true. Also, it would cause some color identity issues as you point out.

"Hi Mark! Have you done the X-Men yet? :) What is Professor X’s color identity?One color: blueTwo colors: white/blueThree colors: white/blue/black" What black aspects does Professor X has?

Professor X has, on numerous occasions, done quite questionable things to keep mutants alive.

You’ve said how with white ramp & card draw, it’s essentially “the more white the input is, the less white the output has to be”. Taxing Noncreature spells is very white, so the payoff being card draw (like Esper sentinel) is a-okay. Is this the case with other effects too? As in, could a black card make treasures off of a zombie entering the field? Could a blue card gain life when you scry? Could a green card destroy creatures when it deals a bunch of combat damage? Stuff like that

The output still has to be something the color does. My point was that the closer to the core the input is, the less close to the core, the output can be. If you want an output that the color is tertiary in, the input should ideally be primary. The input being primary is not an excuse to be out of color.

Amass was in RUB, but mechanically, green likes both singular big creatures and cares about +1/+1 counters. Connive was is WUB, but interestingly, red cares about discard/draw, blue does draw, and black does discard, so RUB mechanically would fit in the pie a little closer. Out of curiosity, what let to bending these two abilities as opposed to sticking to the colors that naturally fit them closest?

Streets of New Capenna was an arc set (aka a color and its allies), so we had to fit mechanics into the wedges.
