How it works
Activate up to seven lands by tapping them, adding at least 2.
Cast Rally the Galadhrim by paying 2 and tapping Skullwinder and Great Whale, targeting Skullwinder
Rally the Galadhrim's conspire ability triggers, copying it, targeting Great Whale.
Resolve the copy of Rally the Galadhrim, creating a token copy of Great Whale.
When the Great Whale token enters the battlefield, it triggers, untapping up to seven lands.
Resolve the original Rally the Galadhrim, creating a token copy of Skullwinder.
When the Skullwinder token enters the battlefield, it triggers, returning Rally the Galadhrim from your graveyard to your hand.
Repeat, tapping the Skullwinder and Great Whale tokens when casting Rally the Galadhrim instead.
