Portalcraft

The first player to cast Portalcraft this game loses
5 Life, sacrifices two permanents and searches
their library for one planeswalker and puts it into
play without paying its casting cost.
Create the game Emblem, "The portal is open
(portal spells may now be played)", or if this
Emblem already existed at the time you cast Portalcraft, remove it.
It led to worlds beyond their possible imagining.
