Temur Sabertooth + Elvish Archdruid + Dynaheir, Invoker Adept

Temur Sabertooth

Elvish Archdruid

Dynaheir, Invoker Adept

How it works

1. Activate Elvish Archdruid by tapping it, adding an amount of .
2. Activate Temur Sabertooth by paying 1, returning Elvish Archdruid from the battlefield to your hand.
3. Cast Elvish Archdruid by paying its mana cost.
4. Repeat.

By leveraging the mana production of Elvish Archdruid alongside the self-bounce activation of Temur Sabertooth, you create a self-sustaining loop that continually cycles the Archdruid back to your hand and re-casts it for a massive surplus of green mana. Dynaheir, Invoker Adept plays a crucial role here too, granting haste so your Elvish Archdruid can tap for mana immediately upon entering the battlefield while also bypassing summoning sickness for Temur Sabertooth's activation, allowing the whole sequence to trigger endlessly.
