Sakashima the Imposter can bounce itself at instant speed which makes for a repeat Nightmare/Horror ETB trigger (this is also why youll notice a Thassa, Deep-Dwelling in the decklist)
When it dies, it leaves behind two 3/3 tokens, one with lifelink and one with deathtouch
Not Dead After All Its not a very exciting card on its face, but considering the amount of play that cards like Undying Malice or Feign Death see across multiple formats, its safe to say that Not Dead After All will see play
But the second they meet with some players penchant for trying to break anything and everything they can in this game, it turns out that these mechanics can become insanely broken
And while you're waiting for those cards to turn up, Talrand , Young Pyromancer , Murmuring Mystic , and Third Path Iconoclast will keep pumping out creature tokens every time your cast an instant or sorcery, slowly growing a token army
It helps keep costs down and allows more casual players access to powerful effects
