Seeing Dredge a strategy, and being the casual scrub I am, I'd recommend a Tormod's Crypt in the side against those decks looking to get milled or to mill themselves. Scavenging Ooze, as great as it is, might not be quick enough on the exile. It might also help against Snapcaster Mage and token decks with Lingering Souls.

I'd rather Crypt Incursion even though Tormod's Crypt is free to cast. Ooze won't come out, if anything, it gets better post board. And as you said, it is great against Snapcaster Mage

Think twice instead of serum visions? With 4 thought scours and three wayfinders you will definitely get in in the yard for free. Also i strongly recommend some amount of hand disruption such as inquisition or thoughtseize. Maybe even a 1 of ravens crime to make top deck lands much better. Man lands are also a must in grindy decks like this such as creeping tar-pit treetop village.

Whoops my bad i did not see the thoughtseizes sitting there.

I definitely was considering at least 1 creeping tar pit, I like the think twice idea, but I would like to further test serum visions for now, the sry seems nice. Thanks for the input!

Gasp 3 Tarmogoyfs, not four?

There was once 4 goyfs. This is the currently list that I used during a PPTQ at my local store. I own the entire list, so thus is another reason I only have 3 goyfs lol, waiting til MMII before adding the 4th again
