As a thought, you could try using Wall of Roots or Wall of Blossoms instead of Wood Elves, both are cheaper and work with Bouncer.

You could try running Energy flux against Trinisphere and some other Workshop decks.  I found when playing it many times; Energy Flux hurt them a lot because Workshop useless for paying the upkeep, and with the amount of artifact mana they need, which they now have to pay for and many times can't .

In every deck it could be used in, you can always run something better, like "counterspells" or Xantid Swarms.  But it could mean that more Powerful Instants and/or Sorceries are coming  in other colors than just Blue and Black.


edit: What I mean by "counterspells" is cards like Force of Will, Misdirection, Mana drain, and Duress etc...
