In all honesty, the fact that Swiftspear made such a quick impression on Legacy makes me want to take a second look at Seeker of the Way in the format, a card that has already made it into multiple decklists in Standard
If you remove Imprisoned in the Moon from a planeswalker after tapping it for mana, you can still activate a loyalty ability of that planeswalker even though it's tapped
Whenever it enters the battlefield or attacks, you return a permanent with mana value 3 or less from your graveyard directly to the battlefield
It also synergizes with Squash should an opponent have a large creature on the battlefield
If you cast Rift Bolt as its Suspend trigger resolves, its alternative cost is without paying its mana cost
This Legendary Creature card also features artwork by Yoshitaka Amano, with both sides being bright and dynamic
