Whenever you attack a player, tap target creature that player controls and goad it. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)
Whenever an opponent attacks another one of your opponents, you and the attacking player each draw a card and lose 1 life.
Karazikar turns the whole table into your weapon: force opponents to swing at each other via goad, draw extra cards (and drain a little life) each time they do, then pick off the weakened survivors. You attack to tap-and-goad blockers, control combat to keep aggression pointed away from you, and grind value while opponents trade resources fighting one another. Close the game with direct damage, big swings, or a goad-fueled combo.
Massive card advantage engine that triggers off opponents attacking each other
Goad warps every combat in your favor and lets opponents do your dirty work
Lives in efficient BR removal and burn, so you can clean up after the chaos
Politically powerful—you point threats wherever you want
Karazikar is a 5-mana 3/3 that dies to nearly everything and is removal-magnet
Heavily commander-dependent; the engine stalls without him on the battlefield
BR lacks ramp, card-draw outside Karazikar, and enchantment/artifact removal
Can paint a target on yourself by aggressively manipulating combat
