Also you're giving up significant percentage in the mirror to play Atarka's Command in the 60. If I were on that plan I'd just play small Zoo. I don't think 4 Shard Volley can realistically be supported.
I just like the idea of having 8x Skullcrack like effects in the 75 the +1/+1 is just a bonus, what is small zoo?
About the Shard Volleys they can be kinda awkward, I just hold on to them until I plan on finishing my opponent (...or when I'm flooded....), its not like you can take your lands into the next match so I just spam 1cc spells at the end.
I love Eidolon of the Great Revel in legacy, in Modern I feel like it makes our good MUs better but is rather weak in our bad/even MUs (since we pretty much kill ourselves via land, so races become horrible against the better quality creatures which your opp. can pump out).Wizards prints the best red two drop of all time -- a Legacy and Modern all-star -- and you choose NOT to play him?
Anything less than four is flat out wrong. The card is AMAZING.
