I had lot of discussion weather I should include cmc 2 cascade creatures or not. This is my first shot at them. "Cycle" with Demon's Attendant, Sphinx's Attendant, (((Dragon's Attendant) and (((Hydra's Attendant))) to mirror the Alara cycle of Angel's Herald and company.

Even in their supplemental set with products "intended" for legacy, Wizards didn't print a 2cmc cascade card.

I do wonder if Wizard's original reasoning was because of the Timespiral cards? I mean, they knew they were stacking these cards right after those 5 no cmc cards... it's possible the restriction to 3 cmc was a reaction to that, directly.

That, and their products "intended" for legacy were just that... intended for legacy. Cascade for 2 is too good for legacy. I don't think it's broken in Standard, though. I could be wrong.

I was arguing back and forth with myself if cascade guys for 2 mana were ok and didn't come to a conclusion. In reality Legacy just shouldn't have a 2cmc cascade creature but in this cube I'm not sure if it's too broken. I mean with cascade for two you miss out on almost all of the value cards, right? So the only thing I'd worry about is cascade (into cascade) into this.
