Your worst case scenario is 3 for a 4 damage spell, which, you just won't cast
Morgul-Knife (Shadowspear) Exxaxl: Shadowspear was one of the cards I first noticed becoming expensive because of Commander
At the time of writing this the full card list has just been released, which means it's time for first impressions in the form of my love/hates
It is nice it has Flash, which makes it easier for you to find that timing, but I think there are going to be too many situations where the Masquerade either does nothing, or is too slow at doing something
With enough creatures and a massive Orc Army, it can be a finisher move
Rashmi, Eternities Crafter was one of the first creatures I thought should be included as she synergizes well with Kalamax and gives you extra value off your instants with her psuedo-cascade ability
