I have just bought Warhamme: Invasion and played a handful of games. I only habe the core set. I have a couple of questions.
1. If a card effect is based on the target's power, does it use the base power, or current power of the card. E.g. there is a Chaos tactic that causes damage to the tare unit equal to its power. If that card was played on orc Boar Boyz and the orc player had an injured unit in play (which increases the Boar Boyz power by 2), would the tactic cause 1 damage (the Boar Boyz base power), or 3 (their enhanced power)?
2. What use is Warpstone Excavation? It is a Support card, so you have to play it in one of your own zones. It therefore corrupts all of tour own units who enter play in that zone. But there are no cards in the core set that make use of your own units being corrupted.
