Scott,

Updated the placement for Threads in the Enchantress matchup, as well as made a quick note regarding the relevant and ideal target actually being the Angel tokens. Thanks for the clarification!

I completely forgot that Argothian Enchantress had shroud. I would probably move it down to "Good" instead of Excellent because of that. As for stealing Angel tokens, that is the entire reason to put them in. I honestly can't say I have extensive experience playing against Enchantress, but the times that I have, my opponent was usually down to the last ten or so cards before they cast Sigil of the Empty Throne. They have to play an extra two enchantment spells for every creature you steal (a token to replace the one you stole, and a token to replace the one you block), so the plan is to hope that they mill themselves.
This is obviously a last-ditch effort, but since no one ever prepares for Enchantress I figured it worthwhile to include some sort of plan instead of holding onto very weak or dead cards.

One question: what is the purpose of bringing Threads of Disloyalty in against Enchantress? Argothian Enchantress has shroud, and the only other creatures I generally see that deck have are Angel tokens (and if they're making those, I don't think Threads will help).
