In the face of high Willpower six, seven, and eight-cost cards, this deck has very few answers
If you exile a token, you get an Incubator with zero counters, which effectively lets you pay two at any time to have a Phyrexian creature die and trigger Brimaz
Return up to two target permanent cards from your graveyard to your hand
Using it for mana for a few turns and then turning it into two 2/2 spiders on the next is a pretty decent proposition , and even though it has sorcery speed stapled onto that effect, it's something for ramp decks to do when their draw is too many acceleration cards and no payoffs
I suggest you look at cards like Lier, Disciple of the Drowned, Past in Flames, and Reiterate to ramp up the spellslinger theme and give your deck some redundancy if youre planning on putting together this list
