Method 2 Heres an alternative method if the first way isnt working: 1

This stamped version of the Koraidon from Temporal Forces is not very special, but it was a limited card that many just couldn't get their hands on, and now it has become gold in the eyes of collectors

(d) At the beginning of your end step, if this permanent was cast for its impending cost and there is at least one time counter on it, remove a time counter from it

Any cards exchanged must be of the same rarity, requiring varying amounts of Trade Tokens and Stamina to complete

It doesn't interact with the Sky Island kit directly, but it fills your hand, which is perfect in this strategy

Doable but probably not as good as some easier options
