Don't believe in no-win scenarios

The smack startles a "d'ow!" out of Clint, but he recognizes the sentiment and agrees with Verity, "yeah. I absolutely owe you, all of you, huge for this."

"I just, what Verity said make me think of something, and you're gonna like it. The energy going into those universes, it's from the Beyonders, and Verity had the idea we could pull it out and use it for our shield thingie. Well, there's somebody who stole energy from a Beyonder before, and it's Reed Richards' biggest rival." He grins for a moment, then drops the grin as he admits, "and also the despotic tyrant of a tiny European country, but I thought you'd find it funny, Reed having to reverse-engineer his worst enemy's old stuff to fix what he couldn't."

Cheating is totally valid to save the world/universe. Clint once tricked Grandmaster out of enslaving Earth with what amounted to a double-or-nothin' bet on a rigged carnival game. Captain America was shocked.
