Each collectible comes with certain Collectible Points. As you use your collectibles in Match Challenges, these Collectible Points decrease by 0.5 with each use. Top-Ups allow you to boost your Collectible Points. The higher your team’s Total Collectible Points, the higher the rewards you can win

Please Note:

Top-Up Frequency: You can Top-Up a collectible anytime you want
Amount: The Top-Up amount can range from anywhere between 1 point and 15 points. However, for collectibles with CP>=90, only a 5-point Top-Up is allowed
Transferability: If a collectible is acquired by a new owner, the new owner can Top-Up the collectible anytime they want
Rarity-Based Ranges: Collectible Points are defined for each moment/card based on the following ranges for each rarity:
- Legendary: 90-100 CP
- Epic: 70-100 CP
- Rare: 30-60 CP
- Common: 15-45 CP
Collectible Points can never be topped-up beyond the higher end of these ranges, and can never fall below the lower end of these ranges
Collectible Points for #1 Serials, Perfect Serials (for e.g. 2000/2000), and Jersey Serials (for e.g. #7/2000 for MS Dhoni) for Common, Rare, and Epic Collectibles can never fall below 45 CP, 60 CP, and 100 CP respectively. Therefore, these collectibles cannot be topped-up as they are already fixed at the upper limit of their respective CP ranges
Collectible Points for Top 25% Serial Common, Rare, and Epic Collectibles can never fall below 25 CP, 40 CP, and 80 CP respectively. However, these collectibles can still be topped-up to reach the higher end of the respective rarities' CP Ranges
