Death has attacked our supply lines, and the warmaster assigned Zaen to defend against Shrink.
If we still haven't heard from Zaen, I would suggest to substitute McSod (who I am sure is eager to defend) and inform the warmaster about it.
As for deck, considering our 2 losses against bonewall-posion combo, I suggest to use a purify-heavy deck and posions for attack.
Something like PoisonDials w/ nova+purify. That should be allowed by the rules, since defenders can use 2 cards from our decks (as we have 2 defenders dedicated this round), so those would be the 2 (nova and purify).
