Your Journey Ends Here

Counters the loyalty ability of the target Planeswalker.
If you do, Exile target planeswalker, then bring it
back into play under its owner's control.
That planeswalker is no longer a planeswalker
and is now an X/X creature where X is its loyalty
value. It retains its color and all its sub-types.
"I am the sustainer of heavenly principles. The arrogation of mankind ends now!"
