I'm not a fan of team-ups but the Machiko team-up in Prey is handled OK. The best team-up (even though I generally don't prefer team-ups) is in Duel. In that comic, the team-up is truly out of temporary necessity
Anyway, I'm glad they're not re-visiting Machiko and are moving on to new ideas. Machiko already as Prey, Hunter's Planet, War, TWW
