what packs have serialized cards mtg Collector Pack Openings for Serialized MTG

The first thing Ill point out is that Ghostly Flicker can (and will) save your permanents from targeted removal

So long as the card presents a consistent use case for one or two mana, then the more expensive door is easily justified as a situational or late game bonus

Its abilities separately can be used to refresh your hand with new cards, stack the top of your deck with just the card you need for the moment, or search for that card and draw it all in the same turn if both Spree abilities are paid for

Given how much it costs I feel like it should exile things and be instant

Clearly, there is some built-in synergy between these two mechanics
