Peach Garden is the deck's only table-wide heal, the mirror of Barbarian Horde and Hail of Arrows. The catch is that it heals everyone who is hurt, with no regard for sides — so play it when your side is the wounded one. In role mode that usually makes it a Lord-team card rather than a Rebel one. It cannot rescue a dying player; only a Peach does that.
Pairs with Hua Tuo (First Aid / Remedy) to make a side genuinely hard to kill, and with Huang Gai (Flesh Wound), who pays HP for cards — Peach Garden refunds what he spent without costing a Peach.
