Akroma, Angel of Fury is the only legendary card with a morph or disguise ability. Considering that morph/disguise is a way to make extra copies of legendary cards useful, is there a reason that the more recent sets have not included any with those abilities?

It allows players to accidentally turn a second one face up and destroy it, so we try not to make that happen too much.

For the vegetables set: Okrama, Angel of Fury/Wrath. Garlich. Rind Rot. Mass Salsify. Mycosynth Lettuce. Thyme Warp. Spinach into Myth. Maize of Ith, Mystifying Maize, Maize's End. Isocorn Scepter. Carrotog. Triscallion. Chord of Cauliflower. Bonegourd/Gourd of Notions. Pepper Smoke. Cucumber Stone. Accelery. Chrome Moss. Animate Bread, Armabreaddon. (Also, have a tribal subtheme emphasizing Birds, Insects, Plants (of course), and Scarecrows.)

This theme will continue as long as you all want to join in. : )

Regarding Akroma, Angel of Fury, it seems a very common occurrence that players expect it to have haste and are disappointed to find out it doesn't. It's very unintuitive to most players that the white Akroma has haste while the red one does not. Why was red Akroma designed this way, and would you have changed it in hindsight?

The white version was designed first and we were trying not to copy the abilities on the red version to make it different. If we knew we were doing a white and red version, obviously we would have saved haste for red. That said, I’m not sure if I had a time machine, I’d mess with a card as well loved as Akroma.
