Galarian Articuno V Ability Not Working

GBsheik

Issue where Galarian Articuno V's ability cannot be used when there are 2 or 1 cards remaining in the deck and enough cards are in hand to meet the discard requirement. No negative status effects on card to lead me to think there's a reason it shouldn't be able to activate.

Also cannot play Trekking Shoes or Professor Research on a 2 card deck.
