Has anyone made a successful Pelops/reflect Arena team for lategame when mythicals are omnipresent?

I wanted to make a no crit Pelops using the reflect dmg.

I was thinking bringing Harima for more passive dmg reduction, some block debuffs (Elva, Siphi?).

But seems like the strategy get very easily countered with any form of CC. So, it would need some cleanse or everyone in Mercurial? Still hard countered by any lockout and Karnage tho.

Was thinking about Bambus for the shield gimmick, but seems way too trolly even with his buff.
