Help to make my Arcum Dagsson deck competitive and general advise for the deck.

{"ops":[{"insert":"This was my first commander a long time ago and i have been playing this deck for quite sometime and now i have been slowly trying to make it more competitive. I know Urza may be a better option but i just love playing with Arcum Dagsson. I would love to keep the forge, lattice, and disk as a lock down win con but it's not as fast as other win cons. I can use some help and general thoughts and advise on the deck. Thank you!\n\n"},{"attributes":{"background":"rgba(4, 4, 5, 0.07)","color":"var(--text-link)","link":"https://archidekt.com/decks/699545#Arcum_Dagson"},"insert":"https://archidekt.com/decks/699545#Arcum_Dagson"},{"attributes":{"background":"rgba(4, 4, 5, 0.07)","color":"#dcddde"},"insert":" "},{"insert":"\n\n\n"}]}
