They need Mind controlers or TK with a better attack. You can also use E/V Selene or U Moondragon to TK/MC a figure next to the bunch, then wholop him for however many

I'd give them the 2000AD Team Ability instead.

Since the MoE/IL are the arch-enemies of the Avengers/JLA, I've always suggested changing their team ability to suit. But instead of free movement, since they're evil they get free attacks. And with the new rules, it works out great.

TheSpirit's MoE/IL: You may give an MoE/IL team member a ranged or close combat action that does not count toward your allotment of actions for the turn.

That means you can use Flurry, BCF, EE, PW, Incap, or PB (as well as regular attacks) without costing an action for your team. You cannot use Phasing, Charge, MC, FB, Hyper attacks, RS, SC, TK, Barrier, Regen, RCE, CCE, or Support (all Power actions). The rest of the powers are unaffected.

This change would make the ability useful without being overpowering. I never liked the massive coordination required of the MoE ability; it just doesn't fit in with the "game for young players" intent WK has. Imagine if the Avengers ability allowed you to move all your AV figures for free only if they all start and end the turn adjacent (in other words, in formation). That's ridiculous. And just look at all the questions that arise from the MoE ability, with Flurry, ranged versus close, incorporating charge or RS... it's too confusing. Allowing free attacks (but not power actions) is clear, concise, and consistent.

Have you playtested this? I do like the sound of it, and I'd be curious to hear how it worked.

There's also the 'free action' version:
The phrasing might need a little work, but that's a significant upgrade. The 'non-free' is necessary so that it doesn't self-trigger.
