1 and 2. The gravel to sell and the oysters to get a sense of how communications with other animals work. If I can communicate with an oyster, my understanding of communication could potentially extrapolate to higher animals.

3. 7 inch teleport is cheater for boxing. Idc about the other ones.

5 to grant me an unstoppable botnet of all the smart toasters out there, 7 to get ansible capability

I will make 10's to 100's of thousands paving roads with gravel and be more than willing to pave roads for people who can't maybe afford it without consequence.

Empty containers may be profitable as well since I could verify which shipping containers could be skipped for further processing, saving hundreds to thousands of hours of time, over time.

What's the cooldown and specifics of #6?

Is it a one-time pill effect or a power you gain? Do you stay looking however you did 10 hours ago forever?

If it's a power, let's say you use it immediately twice in a row. First time: boom. 10 hours younger. Second time: does nothing happen or do you then look 10 hours younger than then how you currently appear? So you look 20 hours younger. Could you keep spamming it indefinitely until you very slowly reach any age you want?

I suppose that depends on whether it makes you look 10 hours younger than you ARE or 10 hours younger than you CURRENTLY APPEAR.

I...I'm spending too much time thinking about this.

7 and 3, no contest. With the ability to see inside containers and short teleport, a person could become a master thief fast

3 and 8. Teleporting is a neat party trick and speaking an extinct language would make me sound smart.

I would take the toaster one just so I could mess with my friends

Do I have to pick two? Because I just want #6

I'm going with 7 and 8. I'd publish a series of books on the Khitan language, get that bumped to the top of google when my name is searched, generally come off as interesting, then attempt to go viral playing shell game with randos on a boardwalk in an attempt to get noticed and land on Deal or No Deal or something like that. Then I'd snag the Guinness Book of World Records title for a couple things along the lines of shell game. Once I have a very modest amount of name recognition, I make a company selling rice cakes in such flavors as Buffalo Wing and Beef Jerky because that's a totally untapped market, in hopes of selling out to Frito Lay or whoever

Play the teleport 7 inches right, and you have a get out of jail free card.

What's the khitan word for gravel?

1 and 8. I seek knowledge. A scholar, if you will.

3 and 5 are a potentially broken combo. In particular if "control a toaster" means control and not just "operate", since then it's basically toasterkinesis, or being able to instantly turn any toaster into a bomb. "teleport up to 10 inches away sounds like it wouldn't be too useful but it does, in principle, allow you to phase out incoming bullets and a fair amount of lateral blade hits if you time it right.

6 and 7 could have some interesting, niche uses in some fields. 6 for example could be used for intimidation if "10 hours younger" is interpreted chronologically: even after taking a serious wound, you'd look pristine for around 10 hours so it might be used to scare or distract some enemies.

I'm... not even sure what 4 or 9 could ever be used for.

5 If you want to see the world burn

Marvel 's writers picking up next super power

Depending on how fast the teleport is, whether there's a delay between uses and whether it causes significant fatigue or other side effects, I might take that. Other than that, it's a toss-up for me between the extinct language and communicating with oysters.

Time to disrupt the gravel market
