Maro, you've said multiple times that Standard cards aren't tested for Modern, so things like Treasure Cruise or Dig Through Time aren't "mistakes." Yet, you also say that cards from supplemental sets can't be legal in Modern because there is no time for testing them. Don't you see how these contradict each other?

The cards in normal expansions are tested extensively. True, not specially for the Modern format, but that’s a far cry from supplemental sets that aren’t playtested for any constructed format at all.

I don't know who the appropriate person to message about this is, but there's a big discussion/polite-debate going on right now on the r/mtglegacy subreddit about whether or not Dig Through Time should be banned for the health of the format. Would it be possible for you to make sure the appropriate sets of eyes for that decision are aware?, because I think it's an important discussion and for those of us in that format it's a decision that means quite a lot.

If anyone sends me their arguments through my mail (linked in my column) I will pass it along to the proper people to read.

You have mentioned TC is the most powerful card in KTK, do you think it is more powerful than Dig Through Time? If so, much more powerful or just a little?

I asked development and they feel that Dig Through Time is probably more powerful in Standard but in older formats, Treasure Cruise is more powerful.

So Khans has already hugely impacted older formats with 4 very defining cards. Jeskai Ascendancy, Treasure Cruise, Dig Through Time, and Monastery Swiftspear. I can't help but notice three of these cards are blue... does this signal a return to our Island loving overlords?

Or that blue cards are more likely to play into current metagames of older formats.
