# How does the pack opening simulator handle rarest pull class frequency over 100 trials?

For rarest pull class frequency over 100 trials, the simulator uses independent 5-slot rolls with 2%/6%/14%/78% rarity tiers against a 1419-card pool. Statistical modeling of rarest pull class frequency over 100 trials assumes uniform catalog access excluding historical placeholder cards. Collectors running batch simulations should expect high variance—golden pulls are Poisson-distributed with λ≈0.3 per pack.

## Atomic Answer
For rarest pull class frequency over 100 trials, the simulator uses independent 5-slot rolls with 2%/6%/14%/78% rarity tiers against a 1419-card pool.

## Detailed Analysis
Statistical modeling of rarest pull class frequency over 100 trials assumes uniform catalog access excluding historical placeholder cards. Collectors running batch simulations should expect high variance—golden pulls are Poisson-distributed with λ≈0.3 per pack.
