Tangled Ruins

{t}: Add {g}{g}.
On your upkeep, put a green 7/7 elemental token with trample and indestructible. If Tangled Ruins would leave the battlefield, exile it and it enters the battlefield into play at the beginning of the next upkeep. You may draw X many cards where X is how many elemental tokens you control. You may do this when the lands enter the battlefield from exile.
