Game of Gods Revolution (D3) Questions and Answers: https://fowtcg.com/posts/68
Question: Do I have to discard three cards if I somehow get to play this card during any End Phase?
Answer: Yes. If you somehow play this card during the End Phase, then the automatic ability will trigger at the beginning of the End Phase of the next turn, as it is a delayed automatic ability.
Question: If I have Zweihunter and 4 other Machines of different names revealed outside the game, do I pay [Darkness] 3 will or [Darkness] 7 wills to play Zweihunter from outside the game?
Answer: You will have to pay [Darkness] 3 wills to play it. The reduction in costs will apply after its alternative cost, just as how it is reflected in the Comprehensive Rules 903.2k:
1) Alternative costs – Effects with “rather than paying its cost”
2) Cost removal – Effects with “without paying its cost”
3) Cost increase – Effects that causes players to “pay more”
4) Cost decrease – Effects that causes players to “pay less”
