Surely an up vote for keeping the cards Theros block, as I was trying to do (keeps cards from leaving in October).
I was thinking about removing
Font of Return, but I didn't know what to replace it with, you helped a bit. Personally I would like to keep
Fate Unraveler and
Grim Guardian, as those cards are at 4 each to increase the probability of drawing them. However, next FNM I attend could change my thinking.
Thoughtseize, couldn't that hurt me more than help me, if going against a burn deck? Sideboard option? I will surely add
Dark Betrayal to my sideboard, as I do not have much of one currently.
Going with the theme of the deck, if I were to remove
Font of Return, what do you think about adding
Spiteful Returned in its place? That would be a favorable early reaction with my opponent, I think.
Again thank you for the assistance!
