Quote why factroy over enclave
Factory comes into play untapped,
activates for half the cost and none of it colored,
blocks and kills a 2/2 while surviving,
and a second pumps the first the turn you play it.
Conclave flies and doesn't die to Disenchant/Naturalize.
Quote strip over port
You don't want that Library Of Alexandria or Bazaar Of Bagdhad tapped.
You want it gone.
Even against Mishra's Workshop, where tapping it during upkeep would be good enough,
you don't want to tie up two of your own mana sources every turn to make that happen.
Just kill the damned thing.
Disk and Morphling is not a combo.
Perhaps Powder Keg?
