1. Each Card indicates its current Level, Rarity and how much progress has been made towards reaching the next level
2. Also shown is the exact benefit you will earn by upgrading i.e. increase in Sell Value of the Machete
3. Amount of Replicate Cards required to upgrade
4. The amount of Influence points needed to upgrade
In the above Example of Blackbeard:
Blackbeard is Level 1 and you need 5 Replicate Cards and 350 Influence points to Upgrade him to Level 2 when he doubles your Workbench Profit.
The progress bar indicates you have 0 cards out of 5, the 1x illustrates your current Profit rate and 2x is your rate after upgrading to Level 2. 0/5 next to the Cards reinforces that you still 5 Cards but the 250 clearly shows you have the necessary Influence points to upgrade Blackbeard.
