Mindbender Spores

The block does not just stop a creature once: it taxes the attacker for the next four turns. Connecting in combat lands four fungus counters on the blocked creature, and as long as a counter remains, that creature stays tapped through its controller's untap step, shedding one counter per upkeep. The design folds the temporary lockdown of a tap effect into the act of blocking itself, so a single combat exchange pulls an attacker out of rotation for four full turn cycles. The cost is steep and immediate: a 0/1 body contributes nothing on offense, and against almost any attacker it blocks, it dies to combat damage on the spot. This is a one-block answer dressed as a creature, trading itself to set a four-turn clock on a single threat, not a repeatable wall that grinds combat after combat. The evasion is what gives the Defender reach it has no right to have: it can intercept attackers in the air that ground blockers would simply let through, then bury one of them under counters as it dies. The counters themselves run backward from convention; here they sit on an opponent's creature as a penalty, holding it down rather than building it up. That inversion mostly stays a curiosity, though it can occasionally tangle with effects keyed to whether a creature has counters at all.
