Rotating Standard cards that see play in Modern

Hey everyone,

With Liliana, Nahiri, Gideon, Spell Queller, Manlands, Eldrazi creatures, etc. all rotating soon, are these cards worth getting rid of and picking up at a cheaper price post-rotation, or do you think these cards see enough modern play to hold their value? I could be wrong, but standard seems to be in a bit of a lull - will the rotation even affect the prices of these cards?

Thanks, guys. Curious to hear what you all think.
