Paarthurnax, the Old One

Flying, haste
If you don't control Dovahkiin, Paarthurnax phases
out.
When Paarthurnax enters the battlefield or phases
in, you may search your library for a Thu'um card. Shuffle your library, then place the Thu'um on top.
{6}{t}: Exile Paarthurnax, then copy Dovahkiin's tap ability. You may cast the Thu'um without
paying it's shout cost.
