Reveal Land

The Shadows over Innistrad cycle of two-color dual lands that enter tapped unless you reveal a card sharing one of their basic land types from your hand. Port Town and Game Trail are canonical examples, with the full cycle covering all five allied color pairs. The reveal-from-hand condition gives them a different texture than battlefield-checking duals: a fresh opening hand with any matching land turns them on, but topdecking one late while holding no matches leaves it tapped. Distinct from land_types.check_land, which inspects the battlefield for the relevant land types rather than the hand, and from land_types.battle_land, which counts basic lands you control.
