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.
