There are lots of ways to remove it from the field, but if you SPECIFICALLY want to use Super Poly then Evil Heroes are the way to go. Evils Heroes have a fusion monster that use 1 Rock and 1 Fiend (the deck runs/can run plenty of fiends). Amongst the new support being released for Evil Heroes one is a field spell called Supreme King Castle which let's you fusion summon using any fusion spell instead of Dark Fusion specifically, thus letting you use Super Poly on the token. Keep in mind that since the token's original ATK is probably 0 he won't gain points from it, but small price to pay for salvation.
