Depending on the fine print that comes with these powers, some of them could be significantly less useless than they appear.

For instance, "look 10 hours younger." Always, or can you do this on command? Can do you it on command more than once? Does the effect stack? Does it include your clothes? Etc. Because if it for example includes your clothes and/or makeup, you could use this to disguise yourself pretty elaborately, or equip yourself with a lot of stuff about your person in advance, then take it off and show up anywhere up to 10 hours later and conjure that stuff out of the air. Imagine the Matrix lobby scene, except you don't have to set off the metal detector on your way through.

Infinite gravel could be pretty OP if you can conjure it at a fast rate, and especially so if you can conjure it at a remote location. Like, above your enemy's head. Or inside his vehicle. Etc. Even if it's just some kind of deal where you present your magic coupon at the Gravel Depot, you could corner the world's supply. There are a lot of roads that need building in the world.

Or if your 7" teleportation range has no cooldown period, you could just chain-teleport pretty much anywhere that doesn't require passing through anything thicker than 7". That's tantamount to flight or super speed running, but you could do it without removing your asscheeks from your chair. Or depending on how the telefrag rules work, you could cause a lot of damage to anyone or anything you wanted by just teleporting through taking 7" bites out of your target each time.
