Activate Mystic Sanctuary and Sceptre of Eternal Glory by tapping them, adding 3
Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and Sceptre of Eternal Glory.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.
This infinite loop is masterminded by the synergy between Sceptre of Eternal Glory and Mystic Sanctuary, letting you repeatedly tap and blink your land base to generate explosive amounts of colored mana. With The Reality Chip giving you access to cast spells straight from the top of your library, you can cast Ghostly Flicker over and over again. Each iteration of this dance resets Mystic Sanctuary to rescue Ghostly Flicker from your graveyard, while Sceptre of Eternal Glory provides the fuel—tapping for three mana thanks to your matching lands—to keep the engine running indefinitely.
