I The Magician
The Magician is all about self motivation, self preservation, and getting things done.
This card represents wanting to achieve something, and having the self-power to do so.
It can also represent taking the first step towards ones plans for the future, and/or personal growth.
Generally, it's about the fact that one has all the things that they need to move forward, and they just need to push themselves forward a little more.
The negative side of the tarot card is that fact that having so much power in thy self to do so, can lead to corruption, and intoxication of it.
It also represents a manipulator.
It doesn't really fit me though

(also. You really love undertale. Don't you?)
