Vorel of the Hull Clade + Intruder Alarm + Thallid Germinator

Vorel of the Hull Clade

Intruder Alarm

Thallid Germinator

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 Thallid Germinator.
3. Activate Thallid Germinator's first ability 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 Thallid Germinator if it has four or more spore counters to start the combo, and you may also optionally sacrifice the Saproling tokens to Thallid Germinator's ability.

This delightful botanical engine turns the battlefield into a runaway growth chamber by exploiting the untap trigger on Intruder Alarm every time new life takes root. As long as your mana-producing creatures can foot the bill, Vorel of the Hull Clade uses that freshly generated mana to exponentially double the counters building up on Thallid Germinator. Each doubling cycle rapidly fuels the Germinator's ability to manufacture Saproling tokens, and every single token arrival snaps Intruder Alarm to attention, ready to untap your entire board for another loop.
