In an attempt at making new and creative deck ideas, one thought that came to my head was Palantiri. How good are they in a deck? What mechanics work well with them? The deck doesn't have to be centered around them, but they have to be an important part of it, using multiple copies and using combos thst rely on them.
Don't really know which exact palantir to use, but I just want to hear your opinions about this. Oh, and this would be in Expanded format or even Casual.
