Does the math on imbalanced factions change if it's just five two color factions with two of them being the same typal/theme. Something like Izzet Weirds, Simic Elementals, Golgari Squrrels, and Mardu (Boros and Orzhov) Vampires?

Five two-color factions isn’t “imbalanced”.

Hey Mark, could cards be reprinted as text less full arts with the same art they already had? I just saw Campbell White's art for the elemental incarnation cycle in the MH3 special guests for the first time, and think that it actually gets hurt by the text box blocking a bit of it, and think it would be really cool if versions with just the art could exist.

It depends on the art ratio.

Hello! I'm a huge mono-Red fan and my special interest is Fire. (I've been a fan of MtG ever since I saw Ashling in a Lorwyn ad. Flamekin are my favorite!!) I'm eagerly looking forward to the reveal of the WildFire Calamity Beast's card! My question is: Can we please get a yes/no/maybe on the possibility of upcoming mono-red Fire elementals?

I can only say we make them from time to time and I expect us to make more in the future.

Blues mind control power suite mist be a total anathema to Red core beliefs of listening to that inner voice(all of a sudden its that Blue mage ordering you about) which always made Threaten effects odd to me as part of its color pie; those would seem more in line with Black mind control (since Nlack would threaten,conjole and blackmail but thats a different topic all together). What was the impetus to put Threaten effects in Red was it part of the old I can use my enemys effects against them(i.e. Red Elemental Blast) or purely a playbalence thing of as a way to deal with big creatures?

Threaten is merely red using its magic to make others as impulsive as itself. Threaten is less it gaining control of their mind and more putting implusive thoughts in their head that get them to act a certain way.

re: infinite clown cards in the library: Previously you've ruled (unless I'm mistaken) that a player with infinite life who is attacked by Infinity Elemental will still have infinite life after taking infinite damage. Infinity minus anything, even infinity, is still infinity.

It seems to me that the infinite clown ruling should parallel that. Once you "shuffle" infinite cards into a library it is only possible that a clown card is on top no matter how many you draw. One card minus infinite clown token cards would still leave infinite cards above whatever discrete unique card was in your finite library. Infinite draws would still leave infinite clown token cards above because (in Magic specifically based on prior ruling as I recall it) infinity minus infinity is infinity.

If I'm incorrect about that prior ruling then this doesn't stand, but to me this seems like the consistent ruling to make with regard to infinities in Magic. It's not a mathematical truth or ruling and I think players trying to approach it like that are bound to get tripped up.

I said you’re just drawing Clowns.

Heya Mark! Some friends and I are planning to build Un-Commander decks, s I have a quick Un-Question for ya! If a player casts Saw in Half on an Infinity Elemental, does the controller get two Infinity/3 creatures? Or is there some other value for their power?

Half of inifinity is infinity.

Would any color have an elemental blast that isn't a color pie violation? My hunch is white is the closest

No one color counters spells and destroys permanents.

Dear Sir, It appears I've happened fortuitously to visit your blog on your birthday. Felicitations! In honour of the occasion, you have been granted the Devour Food ability until the next time it becomes Day. However, you may also need to pay Cumulative Upkeep. My question: what is your favourite creature whose power and toughness as numerals together form your new age?

I’ll say Ancient Greenwarden. I enjoy both Elementals and doubling things.

Hello Mark! Null Elemental Blast does something that any color could do with such efficiency. Is this the signal that “pure colorless” {C} is getting a tiny slice of color pie?

We’re deciding what it can and can’t do, so sort of.

Hello Mark, after the recent MH3 reveals I was looking around and was surprised to learn that Convoke can't cover the colorless only costs on spells like Null Elemental Blast, as it's neither a generic cost nor colored mana by definition. It's admittedly a very niche interaction, but I feel like this is a bit unintuitive. Do you think there would be any value in updating Convoke so you could pay for colorless only mana with colorless creatures?

Assuming we don’t make cards that have both colorless mana costs and convoke, I just don’t think it’s something that will come up, except in hypotheticals. I agree it’s non-intuitive.
