Hayari, Spear-Summoner

Equipped creatures you control gain haste.
Whenever you attach an equipment to Hayari,
Spear-Summoner for the first time each turn,
you may look at the top six cards of your library
and exile any equipment cards among them,
and put the rest on the bottom of your library.
You may cast the exiled cards until the end of
your turn. If you do, they enter the battlefield attached to Hayari.
