I would get rid of amulet for inspiration or Bident of thassa.
Inspiration might be an option, since if I have a Charmbreaker out it could recycle. In practice though the Amulet has worked fairly well for me. Consistently getting to draw an extra card turn after turn is really nice. Inspiration relies on something like the Charmbreaker to bounce back up into my hand, at which point I have to spend the 4 mana to re-cast it. My gut says I'm better off spending the mana up front to get the Amulet running, then enjoy one extra card every turn. I do have a full compliment of Think Twice if I need a quick draw that recycles. I may try switching the Amulets out to see how it plays, though. Thanks for the suggestion!
As for the Bident, I'm not sure that's a good fit for my deck. It only lets me draw when I have a creature deal combat damage to my opponent. In this deck, I can't rely on that happening consistently enough. My foundation creatures are either for defense or to trigger abilities, they aren't for offensive combat. It got to the point where I started holding back from attacking with the Charmbreakers even when they get pumped and it looks like I have a clear shot. Between the black removal that goes after tapped creatures(Assassinate?) and the white one that goes after attacking/blocking creatures, I've been surprised a few times. Now I only risk it if it's for a kill shot. Therefore, my primary source of combat damage are the tokens generated by Talrand. The rest of the damage I do is via Guttersnipes, the Wand, or burn to the face.
