Well, it's never going to look the same I don't think, but you may be able to make it sleeve-legal by flattening it out under a huge coffee table book or something else heavy. Leave it under there for a good while (like a week!), & see if it sits flat. That's all I know to do.
Yeah, water damaged cards are kinda boned. They'll never be the same and after warping, are usually marked cards for life in tourney play.
Have your nephew check this link on how to fix water damaged seige gange commanders I found. Fixing a water damaged Seige Gang Commander
well if it's already ruined, what about tring to iron it, like a shirt.
i would but down something hard on the bottom (not soft ironing board), then card, then some thin fabric, then iron.
it'll never be the same. but if you want to play it, this may make it playable in a sleeve. maybe. ??? worth a shot.

1.) Anyone who thinks cancel is viable should be shot. in the face. with a hammer.
2.) You misunderstand, what I was suggesting was the total exclusion of Spellstutter Sprite, because it just isnt that good anymore.
3.) Understand, Dredge is not really a Magic: The Gathering deck. When a card is playable in it, it doesn't mean it's a tournament playable card. It means it's playable in whatever crazy fantasy world that Dredge operates in.
