Warlord Go Smash vs. Ancestral Engravings

By sammann11, in Warhammer Invasion Rules Questions

I'm playing as Orcs and I use the tactic Warlod Go Smash to attack a zone that has the support card Ancestral Engravings in it. Does Warold Go Smash's action cancel out Ancestral Engraving's action for the rest of the turn?

Warlord Go Smash:

Action: Until the end of the phase, all non-Attachment support cards in defending zones become units with 2 hit points (each card retains its power) with the text 'This unit must defend, if able.' Each card also counts as a support card.

Ancestral Engravings:

Action: When this zone is attacked, this card becomes a unit with 4 hit points (and retains its power) until the end of the phase. It also counts as a support card.

My gut says yes. However, Warlord Go Smash doesn't say to blank the text box of support cards... This would apply if I were attacking a zone with Guard Squigs as well I suppose.

Effect of the action played later overwrites the earlier effect.

Thanks Virgo!
