Whenever an opponent casts a non-creature spell, Cinder Lash deals 1 damage to that player.
1, Sacrifice Cinder Lash: Destroy target artifact or enchantment. Cinder Lash deals 2 damage to that permanent's controller.
A mini, non-legendary Kambal + artifact/enchantment removal against Vault, Oath or Shops. Also this is a proactive play against Shops since you can play it before spheres hit play and leave it there. Also immune to Flusterstorm may count to something.
It can be Revoked so it's a removal that Shops has outs to. But between other removal and Dack, maybe Revoker is not a big threat. The point is that this can hit 3 archetypes, so it could be a premium SB slot or even MD one.
Also important to note that the difference between 1 and 2 damage (Kambal) is huge, since with Kambal in play Tendrils is not a wincon anymore.
