So even though Acorn Catapult doesn't immediately generate tokens upon coming into play, Mishra's Toy Factory can still be used to cast it? And can Mishra's Toy Factory be used to cast Myr Battlesphere (or, say, an Equipment with Living weapon) if there's a Torpor Orb or Hushwing Gryff in play? Can Mishra's Toy Factory be used to cast any creature if Genesis Chamber is in play?

Oops. I confused two cards. You can use Mishra’s Factory to activate Acorn Catapult or to cast Acorn Harvest. You may not use it to cast Acorn Catapult as it does not directly create tokens when cast.

How happy were you to see Acorn Catapult get printed? First squirrel card in years.

I am always happy to see a squirrel card.

How much player demand would be required for Squirrels to 'pull a merfolk' and return to the game, if even for only a single set?

Squirrels occasionally poke their head in a supplemental set (for example Acorn Catapult), but I do not expect to see them in a normal set anytime soon.

If Creative is so opposed to seeing Squirrels in the game, how did Acorn Catapult get by them?

The creative team understands there’s a demand for squirrel cards and found a place for them in a supplemental product.  In all this squirrel talk I feel I might have portrayed the creative team in the wrong light. They are a group of dedicated, talented and passionate people. They have been doing wonderful work for years and a lot of what has made Magic shine these last few years has been their hard work. While I might disagree with them on squirrels, I am wholeheartedly a fan of what they do and Magic is a much better game for that work.

Who did Acorn Catapult and did it ever get past the creative department?

Because it was in a supplementary product and that’s where creative allows us a little more leeway. They did sign off on Acorn Catapult.
