Undersea Ruins states: Once during each player's turn (before attacking), that player may flip a coin. If heads, that player chooses 1 of his or her Evolved Pokémon in play and discards the top Evolution card from that Pokémon, devolving it. My question is, if you used "Baby Evolution" to evolve Wynaut into Wobbuffet, would you be able to devolve it using Undersea Ruins? Correct me if I'm wrong, but as far as I know, as long as Wobbuffet is placed on top of Wynaut it's an "evolved" pokémon, but no matter what, it's never an "evolution card". So, according to that, you should be able to choose Wobbuffet when you flip heads, but you technically can't discard the top evolution card from it, so what would be the ruling?
