冶金召唤 {3}{U}{U}

结界

每当你施放瞬间或法术咒语时，派出一个X/X无色组构体衍生神器生物，X为该咒语的总法术力费用。

{3}{U}{U}，放逐冶金召唤：将所有瞬间与法术牌从你的坟墓场移回你手上。只能于你操控六个或更多神器时起动此异能。

For a spell with {X} in its mana cost, use the value chosen for X to determine its mana value. For example, Clash of Wills is an instant spell with mana cost {X}{U}. If you chose 2 as the value of X, then Clash of Wills has mana value 3, and Metallurgic Summonings's ability will create a 3/3 token. (2016-09-20)
Metallurgic Summonings's first ability resolves before the spell that caused it to trigger. (2016-09-20)

If Metallurgic Summonings's first ability resolves and the spell that caused it to trigger has been countered, use that spell's mana value as it last existed on the stack to determine the value of X. (2016-09-20)
The number of artifacts you control is checked only as you activate Metallurgic Summonings's last ability. It's not checked again as it resolves. (2016-09-20)
