It also has a cool theme that should appeal to fans of the Weatherlight Saga. It requires only two cards to combo off, Sisay, weatherlight captain and Jegantha the wellspring, and both are in the command zone (Jegantha is companion).
How it works:
Turns 1-3: cast mana dorks/rocks, and put Jegantha in hand or cast bloom tender, faeburrow elder, or timeless lotus.
Turns 2-4: cast Jegantha, bloom tender, faeburrow elder, or timeless lotus.
Turns 3-5: cast Sisay, tap Jegantha (or other mana generator) to bring out derevi, empyrial tactician (untap jegantha), tap jegantha to bring out Gideon, Martial Paragon (or a kiora planeswalker) (untap jegantha), bring out oath of teferi and use Gideon again to untap jegantha and bring out Teferi, Who Slows the Sunset (untap jegantha), bring out Samut, Voice of Dissent (untap Jegantha. Your creatures have haste now), tap Jegantha for Aminatou, the Fateshifter. Aminatou can flicker two permanents, so target Gideon twice for at least 4 more Jegantha activations (to bring out Sisay's Weatherlight Crew and Jodah, the Unifier). When you deal combat damage, use Derevi's untap ability on Jegantha to make mana and bring out Legacy Weapon and exile a few things with it.
I always end the turn with Jegantha/bloom/faeburrow/lotus untapped so I can respond to an opponent's spell by cheating something into play such as ertai resurrected or shalai, voice of plenty.
