How it works
Deal combat damage using Rith and the creature with Breath of Fury attached, triggering Rith and Breath of Fury.
Resolve the Rith trigger, causing you to pay 2 to create at least four 1/1 Saproling creature tokens.
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.
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.
Holding priority, activate Phyrexian Altar three times by sacrificing three Saprolings, adding 2.
Repeat from step 2.
This exhilarating loop transforms Rith, the Awakener into an engine of endless assaults by leveraging Breath of Fury to continuously untap your board and grant extra combat phases. Mass Hysteria is the silent glue that makes this possible, ensuring your newly minted Saproling tokens can immediately join the attack without summoning sickness. As Rith floods the board with green tokens, Phyrexian Altar provides the exact fuel needed by sacrificing extra bodies to generate the mana required to repeat Rith's damage trigger over and over again.
