Portcullis 4
Artifact
Whenever a creature enters the battlefield, if there are two or more other creatures on the battlefield, exile that creature. Return that card to the battlefield under its owner's control when Portcullis leaves the battlefield.
(Fortress)
as a potential card in Aggro-Shop sideboards, especially vs Dredge, Oath and Mirror match-ups, and why not vs Fish decks.
Pros :
Its mana cost fits well in Shop decks.
Very good synergy with Mishra's Factory.
Vs Dredge : Narcomoeba, Bridge tokens, Bloodghast and Ichorid would be EXILED.
Vs Oath : if Oath of Druids is on the board and thanks to Orchard's tokens, creatures wouldn't even come into play.
Vs Fish : it could freeze the board with something like Golem and Noble Hierarch.
Vs Mirror : it could avoid your opponent to cast his Trike, Dup or other Golem.
Cons :
You need to get at least 1 creature in play to limit Dredge's development, and 2 vs Oath.
It's definitely NOT a solution vs creatures that are already on board.
vs Aggro, you have to deal with Swords to Plowshares, or you will be self-locked! which is pretty risky. But you can avoid it thanks to Chalice of the Void at 1 and Mishra's Factory, at least in your lucky days...
Anyway, it seems for me to be very good vs Dredge and Oath. But I am now far away from tournament tables to have a good advice on it, that's why I would appreciate the advices of TMD community.
The question is :
In Aggro-Shop builds, wouldn't this card be better than other graveyard-hate cards vs Ichorid? Giving a nice bonus vs Oath which is a tough match-up?
Thanks for your comments and sorry for my poor english
