pokemon cards from detective pikachu TCG: Return Promo 098SV-P SM190 / Promo Card Type / HP / Stage Pokemon Detective Pikachu Jigglypuff #14

Creating additional combats is incredibly powerful but needing to Crew one with Baltheir and Fran, and pay three mana, is a lot of requirements for Standard

Restricting your deck to only mono-blue spells removes options, but you can funnel all that mana into blue card draw spells to trigger the likes of Psychosis Crawler and Ominous Seas to bury your opponents in card advantage, damage, and triggers

I do think they want to slide back and forth through different expressions and play the one that suits their needs at that given time. Of course the Historic format was already unique to Arena as well, if technically playable with paper cards

At the time of writing, this card has a market price on TCGPlayer of $391.67 USD
