Why this card matters
pop
Pop 58 total (21 PSA10) is moderate for a 23.7y card with no reprint risk, but not scarce enough to anchor conviction alone.
demand
No marquee character pull; Trainer support card demand is niche, driven by set completists rather than broad cohort appeal.
artist
Weakness Guard is a minor Trainer card; normal (non-holo) finish with limited standalone art appeal beyond E-Card era aesthetic.
catalyst
25.1% 30d momentum is notable but built on only 4 sold comps—thin sample makes the spike fragile, not confirmed trend.
