So I have taken on the plan to Jap Foil my EDH deck and recently acquired a Top for pretty cheap, but with a downside. This top is creased pretty bad unfortunately and now is showing damage through the sleeve. It is obvious which sleeve is the top. Now I don't ever plan to cheat and my play group says they don't care, but I would rather it just not damage the sleeve. With that comes my questions

I am currently using Dragonshield Brown sleeves and the Top is double sleeved, do you think a textured back sleeve would be better? I refuse to you use any sleeve with a picture on the back, so do not suggest that.

Is there a way to somehow "fix" the crease to make the card lay better in sleeves? Someone mentioned ironing it, but not sure if they were serious or not.

Any suggestions are welcomed assuming they are meant to be helpful.

Thanks guys/girls
