I was thinking lately about Hostage Taker in UB decks sideboard (mostly control oriented lists) as UB is notoriously poor at answering artifacts (really the best option is EE and that only answers <2CMC), and it has applications against mid-range and creature decks that don't have much removal (e.g. CoCo decks, etc.). It can "destroy" a Chalice, Bridge, Cage, Vial, Plating, etc. and can cast most creatures the same turn when you have 6 mana. It's not the best thing in the world, but it's really flexible (and much much better out of a control players SB).

I was wondering what others thought and if they have tried the card. I'll be trying 1 out in the SB in my next modern tourny.
