Vorel of the Hull Clade + Intruder Alarm + Deathspore Thallid

Vorel of the Hull Clade

Intruder Alarm

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

This clever engine turns the humble growth of fungi into a boundless loop by letting every new arrival reset the board. Deathspore Thallid quietly stockpiles spore counters until you have enough to spawn a Saproling token, and that very entry triggers Intruder Alarm to untap your entire board—including your mana producers and Vorel of the Hull Clade. From there, Vorel of the Hull Clade steps in to exponentially multiply the spore counters on Deathspore Thallid, ensuring you can immediately repeat the process to generate infinite creatures, enter-the-battlefield triggers, and mana.
