Pincushion
She's a good if not the best teammate for Bloss comp, she+Bloss+Corbett/Twinleaf = unkillable, 100% skill activation rate and makes full use of her 100%HP passives.

Performance is very high, no dangers, no risks.

I want Pincushion but somehow she've managed to avoid me, just 1 copy and that's enough.
