For Challenge # 028 The cycle is Llanowar Banshee, Diasporan Elf and Llanowar Regrets.

You definitively got the idea right. Pulling the creatures together through use of tribal is a good plan when dealing with this challenge, and upping the evasion type as you go up in rarity is right on target. The individual cards are probably a little too close together, though. If you removed the rarity symbol and asked me which card was the common, uncommon and the rare, I'd have a hard time answering. I probably would have pointed to the Banshee and said "That guy has got to be uncommon. That looks so much like an uncommon. I suppose that makes the regrets rare? But why does common get hexproof while rare has shroud?"

Yeah - maybe the black one shouldn't get any hexproofing at all. But then it's pretty darn weak for its cost.
