Space Stone

Indestructible, if this card is exiled, return it
to its controller's library
{1}: Untap taget land
{t}: Tap 2 target lands they don't untap
during their controller's next untap step
{1}{t}: If you control Thanos, Mad Titan, put
Space Stone in the gauntlet zone
The Tesseract is already on Asgard. It's not wise to
keep two Infinity Stones so close together. -Volstagg the Collector
