Cool Infinite Burn-Mark

this is my first CCG tip so i'll do my best

i came up with this infinite burn combo but not sure if it is legal but 
here it is.
it requires 5 cards two equip spells and three monsters.
the cards are
horn of the unicorn (hotu) or sword of deep-seated (sods) butterfly dagger-elma woodland sprite gearfried the iron knight royal magical library

her's how it works:
you have the three monsters on the field and equip hotu/sods to woodland 
sprite and use woodland's effect to send hotu/sods to the graveyard and 
inflict 500 pnts of direct damage and hotu/sods returns to the top of your 
deck. then
equip elma to gearfried and it  is destroyed and returned to your hand but 
also puts a counter on library.  do this until you can remove three 
counters on library and draw a card with royal magical libray's effect and 
that card will be hotu/sods. u can keep on doing this until you burn your 
opponent's life away.


you can e-mail me, Mark,  at koolio_930@hotmail.com  to comment on my combo 
or chat or duel me.
