A-Bretagard Stronghold

Not yet bracketed (or genuinely unplaceable).

—

Bretagard Stronghold is a GW utility land that enters tapped and produces green mana, with a one-shot activated ability: sacrifice it to distribute two +1/+1 counters across one or two creatures, granting them vigilance and lifelink until end of turn. Its primary appeal is in counters-voltron or plus-one-counters shells where every counter matters, and secondarily in lifegain decks that can exploit the lifelink trigger. The land slot cost and sorcery-speed restriction make it a fringe inclusion — it competes with utility lands that don't enter tapped.
