Hoose, in order to sac off the creature blocked by pilgrim, he has to leave up 3 attacking power and he doesn’t have lethal.

Blasphemous act is card you should be definately picking and splashing. Moan is super solid, but power of the act when you have very strong lategame plan (essence/spider spawning) would make me pick it.

Pack 3 i would definately draft differently:
P3P2: I would pick tribute over unburial rights, you have enough removal to make it work except vs tokens deck and you need something to keep you alive early game. If i was sure i can flash rights every game i could be convinced otherwise, but you only have few targets that are worth to unburial (splinterfright, essence maybe ghoulraiser)
P3P3: Pray upon is terrible pick here – in vaccum its a better card, but in your deck it looks like you could be using it on turn 6 most of the time. Ghoul is early drop that you desperately need and synergizes with chant and ghoulraiser.
P3P7: What do travel preps actually do in your deck? Reneissance is too slow. Scavanger should be a pick – its really solid and a level better than your current 5 drops.

In deckbuilding, put manor skeleton in and cleaver out. And also this is not a deck for travel preps ;]

Also, does your deck really need the Travel Preparations? You’re not an aggro build that can abuse the massive tempo swing, so it seems kinda meh here.
