Well, it's actually a 400pt partially sealed event. 300 constructed, 100 from a booster. One figure from starter. I'm looking forthe best way to incorporate Tellus and two.science police officers into my team. But that requires an investment of 172 points.Giving me really only a few choices to work with. So who works best to complete my box? 100pt Thor, 100pt Switch, 125pt Spidey or dropping a science officer to give me more leeway?

Drop a SciPo. One of them with Tellus and friends can be ugly for the opponent.

That being said, Thor would have a lot of fun counting from other squares. Avx ProfX loves hanging out with the SciPo and Tellus as well.

I'd go with Scarlet Witch. She gives Mystics to Tellus, and adds in a lot of support. That leaves you with 28 points, which you can either use for the Phoenix Force (3 fragments, 2 assigned). If you don't have access to resources, pull in Splitlip - he's the cheapest enhancement available.

I'd personally keep the second SPO. With just one, your opponent doesn't have a lot to fear from just doing a Charge or Running Shot straight at him and eating the one damage - it's not that much worse than Mystics. With two, it's much more punishing, and killing one of them (or knocking him off his power) doesn't fully solve the issue. Besides that, PD team ability only gets better in multiple.
