Vorel of the Hull Clade + Intruder Alarm + Psychotrope Thallid

Vorel of the Hull Clade

Intruder Alarm

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

This ingenious loop turns Psychotrope Thallid into an unstoppable engine by leveraging Intruder Alarm's static ability to untap your entire board every time a creature enters the battlefield. With the board constantly refreshing itself, Vorel of the Hull Clade steps in to rapidly multiply the spore counters on Psychotrope Thallid, generating a continuous stream of Saproling tokens. As long as your mana-producing creatures can foot the bill, you can cycle those very tokens back into Psychotrope Thallid to draw your entire deck and generate infinite mana.
