I am having Nephalia Seakite in my deck, and it has Flash.
I read from MTG Salvation that "Flash is a keyword ability which allows cards to be played at any time you could play an Instant."
But I am not understanding, what I am reading. Does Seakite's skill give me a chance to summon whatever I like (as long as the Mana meets), whenever I like, for as long as it stays in the battlefield?
As an example: With this skill, can I summon a creature of my own in the middle of my opponent's turn?
