It'll be a tough go, and getting tougher without spending a small fortune.
You need 40 Double Take tokens to get the 10 Triple Take tokens you need for the fusion set.....While the Fusion set doesn't show an expiry.
The double take token set (rewind set) expires tomorrow at daily reset.
As of now we still have the "bust" from the high flyers set under the front office tab that rewards a double take token....and those that are included in the themed packs.
With 100 double take tokens you would need $22,500 NBA cash
200 $15,000
Disregard about the rewind set expiring.....I'm an idiot that's when my cool down period expires and I can cash in on it again....Still expensive to get a Fusion player.
