Can Open Dossier work like Eagle Sight + Enhanced Senses?

Hello all. Please help me to clarify:

Open Dossier
Type: Reaction
Cost: 1 blood
Only usable by a vampire who has been chosen for a contract on the acting minion. This vampire attempts to block with +2 intercept and gets an optional maneuver in the resulting combat if successful. Usable by a tapped vampire even if intercept is not yet needed.

For example, if I put some contract in a minion that is not from my prey or preyer and that minion attemps a political action, can I use Open Dossier to try to block that minion, even without eagle sight, falcons eye or other similar effect?

Thank you.

I may be wrong, but I think you cannot, because the card don't say explicitely that you can ignore the normal blocking restriction.

Second tradition have a very similar wording, and I am absolutely sure it cannot be used as an eagle sight.

I agree with your explanation, but I´m still not totaly convinced because in Open Dossier you chose a minion in the contract.

Before you can attempt to block, you must be able to block the action.

6.2.2.1 "Who May Attempt to Block"
This is determined whether the action is directed or undirected. That's it.

If you can attempt to block, then you can play Open Dossier. Also note: Just because you can play Open Dossier, doesn't mean you can play other reaction cards because it doesn't say anything about "as if untapped."

Correct.
