Pentex Subversion controller?

Hi,

Silly question, but who 'controls' a Pentex Subversion when it's on an opponent's minion. The Methuselah who played it, correct?

Basically my question is whether Eyes of Argus' Intercept ability can be used against an attempt to remove it?

Thanks for your patience, because I feel like I'm being obtuse here.

From the rulebook, section 1.6.2:

A master card in play is, by default, controlled by the Methuselah who played it, even if it is played on a card controlled by another Methuselah.

So the action to burn the Pentex is always a action against the methuselah who played it, no matter who it is on.

This is a technical topic, because it works differently for minion cards. From the same rule book, Section 1.6.3:

By default, a minion card in play is controlled by the controller of the minion it is on.

Thanks
