Vorel of the Hull Clade + Intruder Alarm + Vitaspore Thallid

Vorel of the Hull Clade

Intruder Alarm

Vitaspore Thallid

How it works

1. Activate all mana-producing creatures you control by tapping them, adding at least .
2. Activate Vorel of the Hull Clade by paying and tapping it, doubling the number of counters on Vitaspore Thallid.
3. Activate Vitaspore Thallid by removing three spore counters from it, creating a 1/1 Saproling creature token.
4. When the Saproling enters the battlefield, Intruder Alarm triggers, untapping all creatures.
5. Repeat.
6. If creatures you control can tap to produce at least 1, this combo nets infinite mana and you may target any creature using Vorel of the Hull Clade.
7. This combo also nets infinite spore counters on Vitaspore Thallid if it has four or more spore counters to start the combo.

This clever loop turns the steady cultivation of fungus into a dynamic engine fueled by the battlefield-wide untap trigger of Intruder Alarm. As each newly birthed Saproling enters the battlefield, Intruder Alarm freshens your entire board, allowing Vorel of the Hull Clade to continuously double the spore counters on Vitaspore Thallid with the mana generated by your freshly untapping creatures. Because Vitaspore Thallid can readily convert those accumulated counters back into another Saproling token, the loop sustains itself effortlessly while exponentially increasing your resources.
