Mineshaft Spider

The green defensive body has always been a quiet workhorse: enough toughness to hold a ground stall, reach to punish the fliers that would otherwise go over the top of it, and a rate that never asks for a build-around. This one bolts a small self-mill rider onto that frame, and the "may" is the tell that the mill is a bonus rather than a cost. A 3/4 with reach does its job whether or not you fill two cards into the graveyard, so the trigger reads as upside for decks that want a stocked yard and inert text for decks that don't. That optionality is the whole design brief for a card like this: it has to work for players ignoring the graveyard theme entirely and be useful to the ones chasing it, without becoming a liability to either. The mill fuels the standard green-adjacent payoffs (delve, escape, threshold-style counters, reanimation targets that want to reach the yard cheaply), and the reach keeps the body relevant against the aggressive skies that green fixed-value walls are printed to answer. It is defensive glue: a blocker first, a graveyard enabler second, and a card that earns its slot by being neither of those things badly.
