New batch of cards with some potential for vintage

Hallowed Moonlight  
 
Instant - Rare
Until end of turn, if a creature would enter the battlefield and it wasn't cast, exile it instead.
Draw a card.
Better or worse than containment priest? Containment is there all the turns, but can be bolted, stped, decayed, bounced... With this instant you expose to fluster and other countermagic (priest can be played with cavern), and draw a card in the process. With oath works much worse of course, but on the other hand is easier to maindeck since it cantrips itself. I'd say it's gonna see less play than priest, but in more combo or control with few creatures (and maybe even playing tinker+robot) it will be tested.

Infinite obliteration  
 
 
Sorcery - Rare
Name a creature card. Search target opponent's graveyard, hand and library for any number of cards with that name and exile them. Then that player shuffles his or her library.
Saddistic sacrament does not limit to creatures and does not seem play. However
1.This one is easier to cast.
2.It checks hand and grave.
Against oath you take griselbrands (and playing oath take priests if you suspect them), against dredge take golgaris or whatever you want, against bomberman take aurioks... well, too many creatures around. Pair it with probes/duress and so and it's going to take al least one card. I don't think this is going to be a staple, it's in the box of "cute but not good enough", but it's close imho.

Funeral-Blade Predator  
 
Creature - Human Warrior - Rare
Deathtouch
Whenever Funeral-Blade Predator deals combat damage to a player, that player player loses life equal to the number of creature cards in your graveyard.
1/4
Xouman, you are pushing too hard. Yes, I know. A human creature that does not give instant reward or hoses the opponent is not going to have success. Well, I should know at least. This costs maybe 1 too much (we don't like humans that cost more than 2, except maybe trinket and auriok, because they are lovely. Ok, mentor too). I cannot see it played unless in a survival deck or something like that with some help filling the grave. And survival probably wants to combo, not to toy with 1/x creatures. At least it has deathtouch! C'mon, forget about this card. I like the effect, but it's not going to be played in eternal. Bulk rare.
