This clever loop turns Sonic the Hedgehog's punishing speed into a self-sustaining engine, fueled by the terrifying synergy of Odric, Lunarch Marshal. Because Sonic the Hedgehog grants innate haste to itself, Odric can effortlessly spread keyword abilities—most crucially, indestructible—across your entire board at the start of combat. With that safety net in place, Krark-Clan Shaman acts as the pyrotechnic trigger, constantly pinging your own creatures for 1 damage to feed a continuous cycle of artifact sacrifices. Every single instance of damage dealt to your haste-granting team then triggers Sonic the Hedgehog's second ability to produce a fresh wave of tapped Treasure tokens, which immediately feed right back into Krark-Clan Shaman's sacrifice ability to keep the carnage going infinitely.
