Renegade Silent
Goad usually comes with a built-in cost: you hand an opponent's creature back to them pointed at someone else, but that creature still exists, still swings, and the aggression you've stirred up eventually has to land somewhere. This design removes that liability entirely. At your end step it goads a creature you don't control, adds a +1/+1 counter to itself, and then phases out until your next turn. Phasing is what turns the goad engine into something that can't be punished: a phased-out permanent is treated as though it doesn't exist, so while the compelled attacks resolve on opponents' turns, this Alien Horror is not on the board to be attacked, blocked, or targeted. That immunity is more complete than hexproof or indestructible ever manages, since it dodges board wipes, edicts, and targeted removal alike without leaving your side of the equation; a slow value creature that should die to the fights it starts simply is never present to die. The price is a lopsided rhythm rather than a mana or restriction cost. Because it phases in during your untap and out at your end step, it occupies the battlefield only across your own turn: it can attack, crew, or tap while up, but it can never block, because on every turn but yours it is a ghost. A one-sided clock that grows each cycle and vanishes before retaliation can find it.
