Drop Rate Mechanics
The drop rate for cards in ‘Near Monsters’ is governed by a pseudorandom number generator that produces a ‘roll’ between 0 and 255, inclusive. Based on the value of this roll, a card from one of four categories—Land, Rare, Uncommon, or Common—is selected. The mechanics can be summarized as follows:

Land: Roll < 8

Rare: 8 <= Roll < 35

Uncommon: 35 <= Roll < 96

Common: 96 <= Roll <= 255

Land: 3.125%

Rare: 10.547%

Uncommon: 23.828%

Common: 62.5%
Expected Distribution
Given that each pack contains 5 cards and there will be a total of 25,000 packs, the overall distribution for each category at 100% open rate is expected to be:
 Land NFT cards: Approximately 3,906
 Rare NFT cards: Approximately 13,184
 Uncommon NFT cards: Approximately 29,785
 Common NFT cards: Approximately 78,125
True drop rates are random, this is only an approximation.
Per Card Distribution
Assuming uniform distribution within each category, each type of card is expected to appear as follows(100% open rate):
 Each Land NFT card: Approximately 434
 Each Rare NFT card: Approximately 259
 Each Uncommon NFT card: Approximately 634
 Each Common NFT card: Approximately 953
Gameplay
Land staking and gameplay is planned but not implemented.
The card stats are subject to balance updates.
