Pillow Fort

Enchantments and permanents that protect you and your planeswalkers by making it costly or outright impossible for opponents to swing at you. Ghostly Prison and Propaganda force a {2} payment per attacker, Sphere of Safety scales that cost with your enchantment count, Crawlspace caps how many creatures can attack you each combat, and Peacekeeper hard-locks attacks entirely. Overlaps with Tax Effect, the broader group of static cost-inflators; pillow_fort is the narrower defensive subset focused specifically on deterring combat against you rather than taxing every spell or attack generically.
