I've tried them twice. They work well together with Tara using rewind on 33, burying him and then using expedite to unbury him and make him charge, burying and enemy and then pulling 33 back to the rewind marker. Then use Talos/Scion/Nothing Beast/all three to beat up whatever thing you buried.
Generally speaking you'll want incorporeal models since they synergize very well with rewind, being able t reduce the damage to keep the echo marker to 0 and the damage from burnout to 1. If you intend to bury enemies you'll pretty much need 33 since you lost the ability to spam glimpse the void. Talos is often too slow to bury stuff but he's still great if you brought 33.
Though as I said, I've only tried them twice.
