Group Hug decks provide resources to multiple players, offering extra cards, mana, lands, or other benefits to encourage a less immediately hostile game. The strategy often relies on politics before eventually converting all that generosity into an advantage.
Kynaios and Tiro of Meletis hands out cards and additional land opportunities, while Tempt with Discovery invites opponents to join in on the ramp. Group Hug can be genuinely charitable or merely a very elaborate setup for what comes later.
