The community moves this only within the glowing band - it can never detach from real market data.
If Giovanni's Machamp would be Knocked Out by an opponent's attack, flip a coin. If heads, Giovanni's Machamp is not Knocked Out and its remaining HP become 10 instead. This power can't be used if Giovanni's Machamp is already Asleep, Confused, or Paralyzed.
Flip 4 coins. This attack does 30 damage times the number of heads.
“model estimate” tiles are Scrydex modeled values (as of 2026-06-29). Struck-through tiles failed our graded data-quality checks and should not be treated as market truth.

Should I grade this?
Hold for now
Hold: PSA's ESTIMATED economics look positive (~$66.38 at 41% ROI), but no realized sales or high-confidence census back the top grade - estimates alone don't justify a submission.

Comps look noisy: a lower grade was priced at or above a higher one, so values are clamped to grade order and shown as an approximate range.
