Kuokokwa

Reach
When Kuokokwa enters the battlefield, choose a
color. When creatures of the chosen color block
Kuokokwa, it gains Double Strike until end of turn.
Whenever an Equipment you control is put into
the graveyard from the battlefield, you may pay {1} to attach it to Kuokokwa. Exile it at the end of
your next combat phase.
