I have 3 questions on this case:
*Hsien-Ko* (DS2P)
First F discard 2 momentum, add 3 cards from the top of your deck to your card pool face down: Each player returns their vitality to its maximum amount.
1.- To return, is considered to gain vitality?
2.- This ability can be affected by "The Master of Ostrheinsburg" ?
3.- This ability can be affected by Terrain " Ice Coffin of The Sleeping Ancient" ?
Thanks.
