Jon Irenicus, the Exile

Deathtouch.
When Jon Irenicus, the Exile enters the
battlefield you may pay X life. If you do, search
your library for a sorcery or instant spell with converted mana cost {x} or less and put it in your
hand. Until the end of turn, you can play this
spell without paying its mana cost.
Why do you stand for this? Why do you submit to the
flesh, when death is bred in your bones?
