Rith, the Awakener + Breath of Fury + Utopia Mycon + Mass Hysteria

Rith, the Awakener

Breath of Fury

Utopia Mycon

Mass Hysteria

How it works

1. Deal combat damage using Rith and the creature with Breath of Fury attached, triggering Rith and Breath of Fury.
2. Resolve the Rith trigger, causing you to pay 2 to create at least four 1/1 Saproling creature tokens.
3. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to a Saproling token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
4. Move to your next combat phase, and deal combat damage using Rith and the creature with Breath of Fury attached, triggering Rith and Breath of Fury.
5. Holding priority, activate Utopia Mycon's second ability three times by sacrificing three Saprolings, adding 2.
6. Repeat from step 2.

This mesmerizing loop lets you swarm the board and attack endlessly by turning Rith, the Awakener's color-based token generation into a self-sustaining engine. With Mass Hysteria granting your entire team haste, Rith and whatever creature currently hosts Breath of Fury can immediately charge in to deal combat damage, triggering Rith's payment ability and Breath of Fury's sacrifice-and-reattach clause. As Breath of Fury moves to a newly minted token and grants you an additional combat phase, you use Utopia Mycon to turn your extra Saproling tokens into the exact green mana needed to fund Rith's damage trigger over and over again.
