Spellweaver Helix + Regrowth + Emeritus of Abundance // Regrowth + Brass's Bounty

Spellweaver Helix

Regrowth

Emeritus of Abundance // Regrowth

Brass's Bounty

How it works

1. Cast Brass's Bounty by paying its mana cost, creating at least nine Treasure tokens.
2. Activate two of those Treasure tokens by tapping and sacrificing them, adding two mana.
3. Cast a copy of Regrowth from exile by paying 1, targeting Brass's Bounty.
4. Spellweaver Helix's last ability triggers, allowing you to cast the Extra Combat Sorcery, giving you an additional combat phase and an additional main phase this turn.
5. Resolve the copy of Regrowth, returning Brass's Bounty from your graveyard to your hand.
6. Declare Emeritus of Abundance as an attacker.
7. When Emeritus of Abundance attacks, it triggers, becoming prepared.
8. During your next main phase, activate seven Treasure tokens by tapping and sacrificing them, adding seven mana.
9. Repeat each main phase.
