I had forgotten all about the existence of this set. Back in March Topps unveiled a new online exclusive set that's based on the Topps Now brand. It is called Topps Now Future and it's a print-to-order product that was sold as a three-card pack and includes a bonus prize should the predicted 'future' shown on the card come true. For this particular set should the player/team win the 2019 World Series you will get either a 20-card chrome-based team set or a mystery autographed card.
There are three Dodgers' available (Kershaw, Bellinger and Turner) and the total number of packs sold by Topps was 10,910. So, this means that there are about 360 of each of these cards available.
Go here for a complete checklist. BTW, an Award Winners version was made available in April and I hope to have pics of those available soon.
