Wild Legend - Control Warlock

In general if you don't know whether your opponent plays aggro or control I'd prefer to assume it's aggro and play defensive, I would definitely keep a hand of this cards to be able to survive.

I'd usually keep any of this cards in my opening hand against aggro, I know keeping Lord Godfrey might be too greedy considering it's not coming to the board any time soon but sometimes i would rather keeping it than not drawing it at all when i need it as it won me lots of game this way in my climb.

Against control i usually hard mulligan for RIN, THE FIRST DISCIPLE as it secures the game if you can play defensively while playing the seals to fatigue your opponent faster.
