There are plenty of great removal spells just like this that can fit the flavor of any deck that wants them (Eaten Alive for a zombie deck, for example)
For the most part, this is the only color pair that cares about artifacts, so you'll be able to get the key cards from the deck mostly unimpeded
Cyclopean Snare just taps a creature, both Puppet Strings and Icy Manipulators have better taps for less than 3 mana (one can untap creatures, the other can tap down non-creatures as well)
Olivia seems strong with all the cards that increase noncombat damage, like Solphim, Mayhem Dominus and Ojer Axonil, Deepest Might, though that may distract from the theft plan
This is especially true of hard tomove cards, oddities and foils, low-end rares, and most commons and uncommons (with the exception of hot tournament staples)
