COPY - 魔法風雲會

想請教各位大大

Phyrexian Metamorph 非瑞克西亞蛻變妖
3(U/P)
....略
You may have Phyrexian Metamorph enter the battlefield
as a copy of any artifact or creature on the battlefield,
except it's an artifact in addition to its other types.

他複製後的永久物，其mana cost是原本的4呢，還是變成被複製品的呢？

也就是說，棘齒炸彈上需要有幾個counter才能消滅他呢？

同上，

Mimic Vat 擬態缸
3
....略
{3}, {T}: Put a token onto the battlefield that's a copy of the exiled card.
It gains haste. Exile it at the beginning of the next end step.

生出來的token，其mana cost是如同其他token為0，還是有複製到卡片上的呢？
