馭空刃席斐拉

Text:

你可以支付並橫置四個由你操控、具飛行異能且未橫置的生物，而不支付此咒語的魔法力費用。
飛行，繫命
由你操控且具飛行異能的其他生物具有不滅異能。（傷害與注明「消滅」的效應不會將它們消滅。）

Rulings:

• 7/12/2019 To pay Sephara’s alternative cost, you may tap any untapped creatures you control with flying, including ones you haven’t controlled continuously since the beginning of your most recent turn.
• 7/12/2019 To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying (such as Sephara’s alternative cost), add any cost increases, then apply any cost reductions. The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.
• 7/12/2019 Because damage remains marked on a creature until it’s removed as the turn ends, lethal damage dealt to other creatures you control with flying may cause them to be destroyed if Sephara leaves the battlefield during that turn.
