[Guide] Card Ranking Basics
To rank a card you need exact duplicates of the base card - different event versions, or different base OVR won't work, it needs to be the exact same base card!
To have 100% rank success you need:
Original Card
Rank 1: +1 card
Rank 2: +1 card
Rank 3: +2 card
Rank 4: +5 card
Rank 5: +10 card
It is clearly shown in the rank window the percentage chance of being successful - at 100% you are always successful.
Anything below that you risk losing the cards that you are consuming to rank-up the base card.
(trust me when i say that 90% is not a certainty ... not doing that again)
