I was low on Keeper of the Accord when it first came out but I'm hearing good things about it so am ready to test it.

Capsize and especially Deadeye Navigator are great cards, but since both go infinite with Dockside Extortionist, I have to cut half and I want to keep the red 2-drop, since red is struggling for playables in that section. I've liked Docent of Perfection in regular EDH and am curious to see if it can hold its own here, especially since it and Shark Typhoon both support casting spells. I think Into the Story will be good too as a 4-mana instant draw-4.

I realized Seasoned Pyromancer does everything red wants, so I'm going to test it over the rarely-drafted Hanweir Garrison

I looked at the math on wraths in my cube again and decided I needed to cut 4. In each color that had 2, I chose to keep the more expensive wrath to make it a little harder to cast them. So I cut Winds of Abandon and kept Cleansing Nova, cut Toxic Deluge and kept Damnation, cut Blasphemous Act and kept Fiery Confluence/Chandra, Flamecaller.

Vedalken Orrery and Leyline of Anticipation both combo with Seedborn Muse, and I'm finding that having to deal with both of them is a little too much - if the player playing them is in green, players can't let either stick around. I want to keep Leyline to support enchantress decks, and I've never really been impressed with Orrery, so I'm cutting Orrery.

As of now, all basics in my basic land box are snow basics to support Arcum's Astrolabe. I'll be watching to see if it appears in 5 color decks, since it doesn't work with any of the nonbasics in my cube and isn't particularly useful for the Sovereign's Realm player.
