NEVER
Pun Play: I’ll EVER begging for mercy.

My Gameplay: TRADE, PERCH, REVEL, SEVER, FEVER, NEVER
I thought this solve would NEVER end. LEVER was the only –EVER word I didn’t try, but since I used the L in REVEL, I knew NEVER would be the correct choice to seal the deal. May your Sunday be stupendous. On to tomorrow!
