Is the "search for a planeswalker" part of Urza's Sylex tied to its own exile ability? Or can you pay 2 and search for a planeswalker if it is hit by any blink or exile effect?
Urza's Silex's second ability will trigger when "Urza's Silex is put into exile from the battlefield" by any means, not just by its first ability (C.R. 603.2).
