Much like the Pokmon video games, there are many types in the trading card game
Genuine ones stick to exact measurements for authenticity. Beyond pure measurement, two quick non-dimensional checks help confirm what your ruler already told you

This is great because the attack doesn't need to land for the ability to trigger
They are not very good in commander though, and they are only sometimes good in modern or pioneer
