I thought phase 2 wasn't till fall 2019. Does that mean Rob's second printing of phase 1 won't have TSC, 3W or Shipwreck in it? Or am I reading your post wrong?
So for URs:
ALL phase 1 boxes will contain one of: TSC, 3W or SW.
When phase 2 comes out ALL of those boxes will contain one of: TSC, 3W or SW.
After phase 2 has been released (for a while), Rob will start putting phase 1 and phase 2 cards into the same packs/box. When this happens NO packs will include any of: TSC, 3W or SW.
