From a collectors view, rares and mythic rares usually have higher value
Each turn, you can cycle a card, get a free spell from your deck thanks to Unpredictable Cyclone, use Astral Drift to flicker Eternal Witness, and then, when Eternal Witness comes back into play at the end of the turn, you can get the cycler back from the graveyard so you can cycle it again during your opponent's turn to get another free Unpredictable Cyclone card
Ramping is always good, and its why Sword of the Animist is such an auto-include
If Pale Rider is the last card in your hand, then congratulationsyou circumvented its disadvantage (though by waiting until its your last card, you lose out on primary advantage of being undercosted)
