In my opinion, this is an average basic Pokemon card
If youve played Magic long enough, youve heard of the Power Nine, and that public image is worth more than any game function
Then you can drop, for free, an artifact from your hand to the battlefield equal to less than your counter count
As such, "Shadow Mist" can search "Mask Change" or "Mask Change II", then be used as the target of that "Change" card to Summon "Dark Law" or "Anki", netting additional advantage through its second effect to search any "HERO" monster from the Deck whenever it is sent to the GY if done during the subsequent turn
All of these are incredibly powerful relative to their cost, with Ancestral Recall forcing a three card draw for one blue mana, Black Lotus and the Moxes being artifacts that generate mana for no cost, Time Walk giving the player a whole extra turn, and Timetwister letting them draw a whole new hand
