Have you considered Veteran Warleader, Zulaport Cutthroat, Munda, Ambush Leader, or Expedition Envoy in the main deck? I am not a fan of Munda's Vanguard personally so I would replace it with one those creatures. I would consider upping the Captain's Claws count to 3 or even 4 since more Ally triggers the better. I also like the use of Eerie Interlude to get some more Kalastria Healer triggers and as a way to protect your creatures in the case of a board wipe. Stone Haven Outfitter offers some card draw which could be helpful. If you are considering Co-Co then I would definitely drop the Munda's Vanguard for lower cmc creatures to get the most out of Co-Co.
Thank you for the input, Jabilac!
Agreed, if I do go back to Co-Co, I may remove
Munda's Vanguard for something else.
I have to admit, I never even looked at
Stone Haven Outfitter. If, I do up the
Captain's Claws that may find a spot in the deck without question! I think they could replace the Kor Blabewhirl, or
Munda's Vanguard if I go back to Co-Co.
I have tried
Veteran Warleader. It was too dependent on board state, and found it to be a lightning rod. Also, because of cohort ability found it just too demanding in the deck.
Zulaport Cutthroat is in the SB, with
Languish and
Planar outburst. I felt like I was waiting for things to die (reactive play), instead of having a critter to attack (proactive play). Now with SB'ing I can be proactive (willing to take out my own critters with sweepers) and definitely like it in the deck when on those terms.
Munda, Ambush Leader did me more harm than good. I would use it, and have to move Co-Co or another needed card to the bottom with no way to move the lost card around. The removal and utility is small in this deck and it cannot afford to be forced to the bottom without putting something in play, like Co-Co did.
Expedition Envoy, while a 2/1 body for 1 is nice, it did not work out as well as I had hoped. But again, with changes as they are made it may find a spot back in the deck. It is still sleeved and in the "waiting for space" deckbox. ;p
Munda's Vanguard found its way in to the deck by replacing
Serene Steward. Instead of paying white when life gain occurred to add one counter, (and in the long run costing more than cmc 5), I now could just tap a creature not being used otherwise to give everything a counter. Yes, it may be one more CMC than I want to pay to cast, but the overall value in the current form is worth it.
