How would you change VTES? Immunity

Immunity as a Keyword

Immunity already exists as a keyword, usually in reference to damage. It means that a particular type of damage basically cannot be inflicted on the minion with that keyword.  For example "Immune to non-aggravated damage" is equivalent to "No other minion can inflict damage on this minion that is not aggravated".

"Immune to (D) actions" would mean "Other minions cannot target this vampire with (D) actions".
"Immune to political actions" would mean "Other minions cannot choose this vampire during political actions".
"Immune to bloodhunts" would mean "This vampire cannot be the subject of a bloodhunt referendum even if this minion successfully diablerises a minion".


Would you find this to be an easy way to set up a broad keyword (Immune) that would be able to be applied very broadly to have the same effect as the "X is immune to Y" or "X cannot be the target of Y"?

[Edit to include newer ideas]

Immunity to Grapples
I actually, the more I think about it, don't have a problem with a vampire being unaffected by a Grapple and the other minion still affected by it.  The deck intending to play a Grapple is likely to have always intended to work under its constraints.  I also can't see a reason why there shouldn't be the press (at superior) included as well.  Immunity to Grapples would just ensure that the minion with that ability can choose any strike they want, even when a Grapple card is played.

Immunity to Action Modifiers
This is a little more obscure.  However, it would most likely not affect stealth (since that effect is given to the acting minion) but would affect things like "Block Fails", "-x intercept", "tap X", "vampire x cannot block" and so on.  It would basically then come down to the target of the effect.  Does the effect target the acting minion or a blocking/reacting minion. A minion should probably not be immune to all action modifiers, but potentially ones related to a specific discipline (similar to Valerius Maior) "Immune to Presence Action Modifiers" (this would prevent Scalpel Tongue, Perfect Paragon but not prevent Bewitching Oration or Iron Glare).
