Using all this..

cos i'll cut ur leg-end-eerie to give u a bird-in so u'll be pheonix

Leg-end-eerie doesn't even sond like legendary. The whole idea of separating up words to try and make them resemble another word so your pathetic attempt to make it wordplay is 'forced wordplay.' "Leg end eerie" doesn't look or resemble "legendary" at all.

Considering that's what your whole verse is like..

It's all forced wordplay.
