Only two slots left, so it's time to force a couple cards. I chose "Blue Legendary Land" and randomly generated Hydroblast. That upset me for a little while, until I realized that I had a rule that let me pass on 'color hate' and 'cards that tap my opponents lands'. Tapping opponents lands is infrequent in early Magic, but it came up too often, and often lead to bad design. Color hate ain't so bad, but it's far too frequent a mechanic in the 20th century, and keeps clogging up the works. No thanks to either. For what it's worth, I did try to design around Hydroblast without the color restriction. But "Counter target spell, or destroy target permanent" was unlikely to work, no matter how I swung it.

Anyhow, I re-rolled and got Dusk Imp. Took me a little while to figure out how to make it feel rare. I think I would have preferred a 3/3 with a higher activation cost (especially since I want people to feel clever when they activate their Unbender Tine.) I suppose I could always take another stab at the Legendary Blue land to see if I can get something more appropriate.

This is... a fine take on Faerie Conclave, but I'm not especially keen on the way it turns any Spark Spray in the opponent's hand into a Stone Rain. I'd still play it in some decks, though.

My feelings are mutual. It's fair, but not much fun. Which would probably be fine if it was a little more flavorful, but it isn't. Moving to the workbench.
