to clerify a few things, i did not rate your deck lower then i thought it deserved.
a person like like you doesn't yet have a firm grasp on magic as a whole. this deck simply isn't fast enough to win before a bituminous blast
can be played. it's just not. you say it's too slow, even though in the last major tournament all of the decks with the colors ran the card. you are not paying 5 mana just for 4 damage, you are paying it to use cascade, being able to kill a creature and make them take 3 damage and discard 2 cards.mind sludge
is for the sideboard for decks that that draw a lot. i never said it was for main board, so don't tell me i'm trying to make your deck worse when you don't understand the english language.
have you considered sign in blood
? but then again you probably wont understand why i recommended it. i'll explain it because you don't seem to not understand a lot of my suggestions. make them draw, lose two life and then make them discard it, it's risky but any solid deck would shut this deck down since discard isn't that good of a deck type in this new standard.
Check out my stuff and I'll return the favor.
