you always keep 7 cards, no mulligans.
you never start the game instead you want to draw.
you discard a dredger at the end of turn because you have 8 cards in hand.
you dredge next draw step, hit some bridges, narcomoebas etc.
you use
cabal therapy from your grave to make tokens with the bridges and sacrifice narcomoebas.
you attack with tokens till your opponent is
dead.
