Oceanus Dragon

Goad is a red-white keyword by temperament: it turns your opponents' boards into weapons pointed at each other, a political tool that thrives on the chaos of a four-player table. Handing it to blue on a flying body is the interesting move here. The enters trigger does two jobs in one beat: it taps a threat down (a tempo swing, an evasion-blocker removed, a would-be attacker stalled), and then forces that same creature to attack elsewhere on its controller's next turn. The tap is the immediate defensive value; the goad is the delayed offensive value, aimed at someone across the table. Blue rarely gets to shape combat this directly, and the trigger keying off entry rather than an activated ability means the effect can be rebought through any flicker or bounce loop, turning a single creature into a repeatable tapper-plus-instigator. The 3/5 frame is built to survive: five toughness blocks most of what a goaded creature's controller might send back, and flying keeps it relevant on offense while the ground grinds. It belongs with the cards that weaponize an opponent's creatures rather than answering them outright, and it does that work in the color least equipped to remove threats permanently. That mismatch is the whole point: blue would rather redirect a problem than deal with it, and this hands the redirection to the color that needs it most.
