this deck is bad it has no defence and with oracle or beowulf on the field during stand by phase you can quickly burn yourself to zero and with a lot of monster removal cards it happens
You keep losing because you didn't make the effort to obtain several copies of the UR/SR.
Instead of saying that make the effort of using your pocket money.
triple swirl slime doesn't make a difference when you just get your monsters banished, and dark contract with cosmic cycloned, then proceed to have your graveyard turned to skull servants ending the chance for a comeback play assuming you aren't swung for game right then and there, its fun but not competitively viable above platinum
Your cards getting banished or changed to skull servant isn't an issue when you have multiple copies of them.
Like a Blue-eyes deck has less problem with a banished blue eyes if there is 3 copies.
Make the effort and buy another copies, it will not even cost as much as a fully priced pay to play game, totally worth it.
it's comparing apples to oranges, blue eyes rarely uses graveyard and only on your turn to get BEAWD for re up. the D/D/D cards we have released to us you need to make half your plays by recycling graveyard cards for fusions or synchros, your solution of getting more cards doesn't help the issue that they can't be used to full potential before they get skulled by your opponent and become useless
