Namely, it will still cast auras to buff it's creatures even if I have a Seal of Removal on board, despite having other things it could play in hand. I don't know if anything can be done about this, but it would be very helpful if it could. Choosing to tap all your mana to put an aura on a creature while staring at Seal of Removal (or Seal of Doom for that matter, any kind of obvious removal), despite having other things it could play is magnificently counter-productive.
