MTG Standard help. Trading Post problems.?

Well, black can't deal with artifacts or enchantments, so you will need to go for a Blue, White, Green or Red solution. Or get them with Discard before they can play it.

Blue has bounce, which is a short-lived, but does open up Discard. White has pretty solid Removal, as does Green and Red. You already have cards than can put out white in your deck, so they'd be the easy choice to sideboard if you don't find anything in blue you want.

White would be a good answer to artifacts, but don'f forget you have two sources of white mana in your deck so that's a very small chance of drawing what you need to be able to cast the spell if you can even draw it during a game.

Maybe take out all blue and replace it with white so you have that artifact control if it's that much of a problem? You only have three instances of blue in your deck, the Metamorphs can use the Phyrexian mana, so why not take out the small amount of blue and replace it with white?

Sometimes you have to give up a bit of power to be able to deal with different situations during the game. But I only recommend this if your meta is that heavy in artifacts.

U could take out ur isolated chapels and ur vault of the archangels for woodland cemetery and a u could use Acidic Slime or naturalize to destroy artifacts.
