6 rewinds are too much, u risk to lock yourself against pdials, same for 6 nightmare: 5 are enough
only 2 copy of sov has no sense
always run some steals, to punish swallow decks with sop and for stealing arsenic against pdials
u can think to add one or two vampires, just to be safe against pdials, but the best choice is to add more sov (unupped sov does the same work); autoquit with pdials, swallow is too slow for closing the game in less than 10 turns and sof can't break all your sod
in the first 3 days almost nothing can break this deck (if u aren't super unlucky), after the fourth day (or below 150 hp) this deck starts to be weak against rush decks like freebirds or chaos/brave wyrms, but almost no one use that in plat
