Planar Incision

Removal that isn't. The line reads like a two-mana kill spell right up to the phrase "under its owner's control," and that qualifier flips the whole spell inside out: this exiles and returns, so it never actually removes anything. What it does is flicker, and the flicker cuts both directions. Aim it at an enemy threat and you strip the auras, equipment, and accumulated counters off it, pull it out of combat as a new object, and hand it summoning sickness for the turn; the tax is that the creature returns a little bigger, since the +1/+1 counter lands no matter whose permanent you targeted. Aim it at your own board and the same reset re-triggers every enters-the-battlefield ability and stacks a permanent upgrade. That counter is what keeps this from ever being a clean answer. You cannot use it as spot removal, because the target always survives and always grows, so every cast is a negotiation about whether the reset is worth feeding your opponent (or gifting yourself) a permanent point of stats. Calling it a flexible utility instant oversells it; the honest read is a two-mana manipulation tool that trades a hard answer for a soft one and never leaves the target smaller than it found it.
