If I have a fully countered up {archmage ascension} and my opponent has a {cosi's trickster}, if I were to draw multiple cards ala {blue suns zenith}, is it a search and shuffle for each draw as far as trickster is concerned or would it just be one?
Yes you would shuffle for each one. Say x was 5. You decide to search for all 5 draws. You would shuffle 5 times. Even though you would probably be allowed to skip each shuffle and grab 5 cards, the creature would still trigger for each one.
RESOLVED
A search and a shuffle, and a counter for trickster, foreach card. You don't need to take all the shuffles, though, you are allowed to take a shortcut and search for all together with a single shuffle, but this is a shortcut only and the game accounts for each shuffle you should have made
Thought so, thanks for confirmation!
