This card has been such a boon for protection. You can leave it on big minions and just chip away at their health casually while you block their damage. I found it synergized as well with Jump Flip and Side Step, so you can avoid using a basic defense to trigger the card. Also amazing for Change of Fortune. If you're finding you're having trouble dealing with minions and protection, I highly recommend this card.

Under Control seems like a worse version of Powerful Punch, First Hit, and the like. This could work with Nightcrawler, who can defend without exhausting (with Bamf), so he can defend against the villain and a minion. It can also work with Change of Fortune. Under Control is worse because you can’t activate it without defending against a minion, but all the rest you can just activate. It can activate multiple times –that’s nice. So if you’re up against the Dragon (Mojo Mania) you could defend a bunch and eventually take it out.
In multiplayer, you mostly want to defend the team against the villain, so it seems more of a solo card, though I’d love to see Valkyrie play it.
