Hello everyone,
I would like your opinion about the following game situation:

I have in play:

"Lord of Change" (Players play with the top card of their decks revealed. You may play the top card of your deck as though it were in your hand.)

and

"Manfred Von Carstein" (Destruction only. This card gains 1P For Each resource tokens on it. Action: Discard a card from your hand to put the target unit in an opponent's discard pile on the bottom Of His deck. Then, place a resource token on this card.)

If the opponent has, for example, 10 units in his discard pile, can I play the action of Manfred and discarding 10 cards from the top of my deck and give 10 power to Manfred?
In practice the "You may play ..." given by the effect of the 'Lord of Change” also includes the action of the "discard" cards, or only the “put into play” action?

Playing a card means that you pay all costs and bring a card into one of the three zones. So discard isn't equal to playing a card. Under this condition, I guess, Carstein will not works with the Lord of Change in that way you described.
