Yamask Best Moveset

85 Defense is noteworthy for a pre-evolution but 38 HP undercuts it badly. 30 Speed and 30 Attack leave the moveset with no damage output on maximum cooldowns. Ghost TermStab barely exists. Cofagrigus's 145 Defense is the goal.

Shiny Yamask

Yamask goes from pitch black to a lighter grayish tone. For a ghost carrying its own death mask, a little less darkness doesn't change the vibe much. Forgettable C tier.

How do we research these odds?

We check every game where a shiny is possible, then rank each one by the best method available in that game, so the row at the top is the fastest route overall.

Odds marked verified are cross-checked against multiple independent sources before we publish them. Where a rate is not yet confirmed we mark the row pending rather than guess a number.
