Narset of the Ancient Way

[+1]: You gain 2 life. Add {U}, {R}, or {W}. Spend this mana only to cast a noncreature spell.
[−2]: Draw a card, then you may discard a card. When you discard a nonland card this way, Narset deals damage equal to that card's mana value to target creature or planeswalker.
[−6]: You get an emblem with "Whenever you cast a noncreature spell, this emblem deals 2 damage to any target."
