Jaco,

 The short answer is I like the utility of being able to tutor but dislike losing lock pieces to do so.  And smokestack further enforced the incremental ways I was looking to lock my opp out.
 
The rector player was playing a list almost identical to what you posted with some substitutions in the board. 

Please check your inbox, I sent a message in regards to submitting a piece to EC.

For those interested here is my unconventional take on a Forgemaster Stax list.  FWIW, Patrick Ohren was on a Gifts Academy Rector Flash deck.
