Basically you can have more than one of a same secret on board while this card is on the battlefield.

"Lets mix things up a bit"

The effect is quite similar to Kabal Chemist

Inspired by: https://wow.gamepedia.com/Druid_of_the_Talon_(Warcraft_III)

While Druid of the Talon also has a crow form, I liked it better as a pure spellcaster in the game. The Cyclone ability is a good deal different in Warcraft, more like a Freeze effect, but Freeze doesn't fit in Druid, and this effectively also makes an enemy non-threatening.

Edit: Forgot the rarity gem.

Elven Archer

In W3 Night Elf Archers can mount Hippogryphs to become one unit.

Flavor: They're called WATCHERS, not EXPLORERS, for a reason.

Why yes, it obviously has the potential to bring forth/back a Death Knight as it did in Warcraft 3 -- thus the "Wild" and "legendary Warlock card" specifics. And a Dreadlord, too (Mal'Ganis).

+ = Awsome Minion

The idea being that you have to spend mana(gold) each turn if you want to buy a (goldshire) footman.

The Ancient One

Also, for the text of the card I referenced Blood of The Ancient One

For Clarification:

X2 of these in play will bring your mana total to 12 past turn 10 - at the cost of two minion spaces on the board.
