Vorel of the Hull Clade + Intruder Alarm + Thallid

Vorel of the Hull Clade

Intruder Alarm

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 Thallid.
3. Activate 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 Thallid if it has four or more spore counters to start the combo.

This brilliant botanical engine transforms slow token generation into an explosive loop, fueled by Intruder Alarm's global untap trigger whenever a new creature enters the battlefield. As each 1/1 green Saproling token spawns from Thallid, the Alarm resets your board so that every mana-producing creature and Vorel of the Hull Clade can ready themselves for another cycle. By spending the generated mana to activate Vorel of the Hull Clade, you rapidly double the spore counters on Thallid far beyond the three required to sacrifice them, leaving you with infinite creature tokens, boundless ETB triggers, and as much mana as your other permanents can yield.
