Bottom 30 Challenge -- Beat a level 395 team.

STUNNING -- What are the best stuns in the bottom 40? All the best Stun skills are . Maintaining a stun is important against high-level freaks, so Cap and Daredevil go to the top. When alliance members ask for Team-ups, 1* Black Widow is quite good.

MN Mags and Captain America can be surprisingly good against high-level foes.

MN Mags pairs up very well with Mystique. His makes for her, her makes for him. Add in Captain Marvel for a stun.

Since when is single target stun enough to stun a team with 3 guys to move the board? Or are we assuming the 395 team doesn't have 3 guys that can move the board? This can significantly reduce the difficulty of the challenge. You can't even stun a team for longer than 5 turns even if you started out with 30 AP of whatever color you need (3 staggeered Winow's Stings), let alone actually trying to collect that AP before your team gets rolled over. Realistically the cheapest team stun you're going to get is 6 blue AP for 2 turns from Captain America which requires you to have 36 blue AP at some point (you can stagger the Peacemakers to account for that you can only have 30 at once), but even if you could start with 36 blue AP, you're not going to be able to collect 6 blue every 2 turns because the board cannot possibly keep up with that rate of replenishment. Nothing else is even close to this ratio.

Correct. Depends on the Goon ratio. With 2 Goons, stunning the non-goon can be a key to winning. Hailstorm, Cap's shields, She-Hulk's steals are also helpful.

If there are no goons, it is absolutely vital to take down at least 1 opponent before a Stun strategy has any chance at all. Pretty much only Daredevil or Captain America can do it. MN Mags or IM40 and Boosts are needed for the blue. The first goals are to get for a Magnetic Flux in a good spot, and to kill one opponent. I've done this against Level 395 Ares, Daken, Yelena. Ares was my first target, and first to stun. Polarity Shift was used to remove from the board except for the red tile I wanted (which also nerfed Daken). Everything went to damaging and stunning Ares, since he was instant Death, and denial for Daken. When Ares finally toppled, Cap was my only character standing, but he had a lot of bouncing shields on the board. Still took forever to take down Daken, and then to finally take down Yelena. It's very hard to do, but possible.
