Seeker of Slaanesh

Compulsory-attack effects are an old red idea, but most of them targeted a single creature and dared it forward: think of the curses and enchantments that force one blocker or one attacker into the red zone. Allure of Slaanesh does the systemic version. It levies a standing tax on every opponent's combat step, obligating each of them to send at least one creature forward whenever they can. That reshapes the political geometry of a multiplayer game more than any single-target lure could. Defensive players can no longer sit behind untapped blockers and stall; their board is forced open on their own turns, which means the creatures they attacked with (barring vigilance) are absent when it comes time to guard. The 3/3 with haste is the smallest part of what this card offers; its real output is the pressure it pushes onto everyone else, converting stalled boards into obligatory brawls and letting an aggressive deck feed on the resulting attrition without spending resources. Pair it with punisher effects and damage-on-attack triggers and the tax compounds, but even alone it turns opponents' creatures from a wall into a liability every combat, a quieter and more durable way to crack a stalemate than any one-shot removal spell.
