Well, firstly he'll need to know some.
It's possible he'd know some stuff from his time as a stage magician, but nothing too near the level of a dungeon punk world.
Like those boxes that are sawn in half, the boxes that have swords run through them, admittedly those would be tricks that people would know worked but wouldn't be entirely sure why, kinda like the difference between real-life alchemy and chemistry.
Anyway, the whole light or dark side of magiteck really just depends on how you use it or what you know. It's not really that biased either war, magiteck is much less corrupting or purifying, it really depends simply on who uses it.
But yeah, you need to actually learn this stuff.
