So 6 mana and 2 cards at the very least for a 2 mana random secret? Kinda meh, but the card itself has decent stats even without a secret in case of emergencies. Could fit into mid-range secret hunter or maybe even control hunter with secrets, if either of them are ever a thing. Not too bad, but not too good either.
Weird that Professor Putricide is a hunter card tho.
I... guess because he's turning into some kind of beast/dino in the art? Some kinda Scary Monsters stuff going on? Only reason I can think of for him being a Hunter legendary. The effect also doesn't make sense for the character, really.
But the statline is fair. I suppose the dream is an uncontested Cloaked Huntress into this gets you a nice secret tree going, but how often is that going to happen? If it sticks, it's good, but if it doesn't then it's vanilla stats... and that's not gonna see a lot of play. Hard to judge for certain, but it's possibly good.
E: Yeah I guess dropping it on Turn 6 with Freezing Trap can be a decent enough combo, but hard removal counters that well enough. Still a bit skeptical, especially since Turn 6 is Savannah Highmane territory, and I'd rather play that than the previously mentioned combo.
Playing Cat Trick and getting Freezing Trap or Explosive Trap will make it very annoying. Not even speaking about the value when you can stealth it or play Secrets more than once with it. Cloaked Huntress is something i can't imagine right now. Hunters aren't known holding many cards for combos imo.
And love the art btw. Bringing back some Mad Scientist memories.
