Why this works

Giving Phantom Assassin Overcharge is a simple way to get more attacks out, which means more chances for Coup de Grace to land a fight-winning crit. Tether also helps her stick to targets after a Phantom Strike. The problem is that Io offers very little to help PA survive her biggest counters, like heavy magic damage or lockdown. If Phantom Assassin gets stunned and focused, the Tether regeneration is rarely enough to save her before she gets blown up, making their engagements very high-risk.

The game plan often centers on using Relocate to bring PA to a fight or an isolated target. This can secure kills on enemies caught out of position. The risk, however, is that PA has no reliable escape if the gank goes wrong. If the enemy team reacts quickly or has good stuns ready, she can be locked down and killed the moment she arrives. This makes the duo highly dependent on catching enemies off guard, and they can struggle against teams with strong defensive tools and map awareness.
