Chord/Tab song: Black Mermaid

I'm an amateur guitar player and this song uses chords that I am unfamiliar with.
I could be completely wrong about these chords, but this is what I hear when I
listen to it and I can sing the melody over these chords and it blends beautifully.

The chords in this song are strummed using only E, A, and D strings while keeping
the three higher strings G, B, and e muted.

chords used:

E A D G B e
G: 3-2-0-x-x-x
A: 5-4-2-x-x-x
D: 5-5-4-x-x-x
