Planeswalker - Saheeli
+1: Scry 1. Saheeli Rai deals 1 damage to each opponent.
-2: Create a token that's a copy of target artifact or creature you control, except it's an artifact in addition to its other types. That token gains haste. Exile is at the beginning of the next end step.
-7: Search your library for up to three artifact cards with different names, put them onto the battlefield, then shuffle your library.
+1 Isn't card advantage and I can't think of any common good use of her -2 (maybe duplicating a Young Pyromancer/Mentor to generate more tokens? I don't know, she's not bad, but seems way worse than Dack at first glance.
