[疑問]請教關於WW昂行潛獸瑞克蕭異能的使用方法

[fantasy]

Wrexial, the Risen Deep昂行潛獸瑞克蕭
:m3
傳奇生物 5/8
Islandwalk, swampwalk
Whenever Wrexial, the Risen Deep deals combat damage to a player, you may cast target instant or sorcery card from that player's graveyard without paying its mana cost. If that card would be put into a graveyard this turn, exile it instead.

1.請問選擇使用那玩家墳場的巫術或瞬間
如有其他異能是否能一併使用
EX1 有增福或是多重增福
Burst Lightning
Instant
Kicker :m4 (You may pay an additional :m4 as you cast this spell.)
Burst Lightning deals 2 damage to target creature or player. If Burst Lightning was kicked, it deals 4 damage to that creature or player instead.
我能否支付增福費用

EX2 有地落
Rest for the Weary :m1
Instant
Target player gains 4 life.
Landfall — If you had a land enter the battlefield under your control this turn, that player gains 8 life instead.
如果本回合我有下地,是補4還是補8

2.請問是"使用後將原本那張巫術或瞬間牌移出遊戲(這回合)"OR"使用後除了將使用後將原本那張巫術或瞬間牌移出遊戲,之後那位玩家如有使用同一張牌也將之移出遊戲(這回合)"還是其他解釋

拜託各位大大幫忙 3Q

小菜鳥路人經過～

1. 記得像類似這樣免費施放咒語的異能，指的是施放費用免費，增幅可以，只是要另外支付！
反正就當作正常使用，只是有人幫你付了施放費用而已！

當然地落也是看自己是否有地落過～

2. "If THAT card would be put into a graveyard this turn, exile it instead."
都強調是"那張卡"了，我想指的就是只有那一張咒語卡吧～
如果是同名的話，應該會有另外不同的敘述。。。

以上是個人想法，歡迎指正～^^a
