Trying out vengeful dreams. Removal is great of course, but it also has nice synergies with the white reanimator archetype.
Thalakos Seer is interesting as a blink bounce target to get a draw every time. Can also draw your deck with some Aluren loops. Of course it has shadow too which has some good combos. We will see how it is. Repulse out because too many of these effects in at the moment.
Imperial Seal to help out with all the weird combos in right now. Phyrexian Tower just isn't needed, plenty of good sac outlets in the cube.
Words of War is always mediocre. Spellshock back in to fill its role at least in more aggro decks.
Eladamri's Call just never fits. There are plenty of creature based combos in the cube at the moment, but WG never fits in the decks well. It is fine in the enchantress deck to fetch one, but really not needed.
