Whoa that’s a good card! It’s like Mad Scientist value. While it’s better in a mass secret deck like wild secret mage, I could see it used to tutor out Ice Block when combined with Ice Barrier in wild.
Looks good, but given Bellringer Sentry saw zero play I'm not sure this is a definite hit in standard (yes I'm aware that was Paladin and Paladin secrets are WAY worse to cheat out than mage or hunter secrets!). Wild may be a different story though, especially as Ice Block is such a reliable trigger for this.
