You have cast your commander from the command zone at least twice. You have a way to cause a land to enter the battlefield under your control. Mana needed:

Steps

1. Cause a land to enter the battlefield under your control. Springheart Nantuko triggers, causing you to pay to create a token copy of Jyoti.
2. Put the token Jyoti into your graveyard due to the legend rule.
3. The token Jyoti's enter-the-battlefield ability triggers, creating a 1/1 Forest Dryad land creature token for each time you've cast your commander from the command zone this game.
4. When the Forest Dryads enter the battlefield, Springheart Nantuko triggers that many times.
5. Holding priority, activate two Forest Dryads by tapping them, adding .
6. Resolve the first Springheart Nantuko trigger, creating a 1/1 Insect creature token.
7. Repeat step 6 until there is only one Springheart Nantuko trigger remaining.
8. Resolve the final Springheart Nantuko trigger, causing you to pay to create a token copy of Jyoti.
9. Repeat from step 2.
