This thread is for discussion of this week's Latest Developments, which goes live Friday morning on magicthegathering.com.
Akroan Mastiff is hardly the most effective tapper ever. I mean, sure, it's playable, but at 4 mana it's no Goldmeadow Harrier; often it'll come down late enough that just tapping down one guy might not be enough.

In regards to the 1-mana Blue cantrip, perdana, sans-serif">ersonally I have doubts that something like a functional Opt reprint with scry (that is, a 1-mana Blue Instant that says "scry 1, then draw a card") would be problematic for Modern, but even if it was, why not just print Serum Visions? You can't cause problems for Modern with a reprint. Before anyone claims that the serum is something from Mirrodin, there's nothing to prevent you from just reworking it into some different kind of serum that gives visions.
Sam mentioned in the article that they didn't think Standard needed a 1-mana blue cantrip either.
