Does anyone use this?

[Destore117]

Have 2 {Unknown shores} sitting around and was wondering
Are they actually useable? Or should I just get something else.
If so. What?

[Rass]

I've only used them in sealed or draft

[Kaleo42]

I have used two in a highly competitive {trading post} deck and in a izzet control deck I am working on.

They would be nice in an EDH deck or really any tri or more colored deck.
