I want Darwin Claus to bring me random mutations that may or may not be beneficial to my survival and my capacity to create offspring.

Random mutations are the least potent source of change in evolutionary mechanisms. So much so that some experts don’t even consider them as one.
Reinforcement of already existing traits through variation between individuals under environmental preasure is the main mechanism. (i.e. when food sources are high, individuals with longest reach are the fittest).

And the longest reach comes from… random mutation?

How to say that you didn’t read Lamarck without saying that you didn’t read Lamarck. Even Darwin agreed with him.

You seriously believe in Lamarck? Like, I don’t know, I’m not a native speaker, maybe I’m missing something.
How many fucking times do we have to repeat this: TRAITS ACQUIRED DURING LIFETIME ARE NON-INHERITABLE
If you lose your fingers in an industrial accident, your children aren’t going to be born fingerless, are they?
Giraffes don’t have long necks because one little giraffe long, long ago tried really, really hard to grow a longer neck, but because giraffes who had been born with longer necks could compete better than those without, and pass on their genes. And they got those necks due to mutations.
Environmental pressure selects for benefitial mutations, while the mutations themselves are random. That’s literally the mechanism of evolution through natural selection.

Lamrack has been disproven

There is natural variation between individuals.

Natural as in naturally occurring mutations?
