Navigator, sharded with Chance and Immortal talismans is a great toon. Even as a natural 4 star. ( I mean IE is a 4star too )
VHE with Immortal and 3 greens is good. Put a blocker like WUR on the same team and he's more beneficial. Admittedly though, he's nowhere near the beast he was 3 months ago. He's now a tad weak against Iron, PoM, 7S, etc. But in PVE VHE can still be good.
