Vorel of the Hull Clade + Intruder Alarm + Elvish Farmer

Vorel of the Hull Clade

Intruder Alarm

Elvish Farmer

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

This loop turns a simple fungus into an engine of exponential growth by using Intruder Alarm as a constant reset switch, untapping your entire board every time a new creature arrives. Elvish Farmer provides the entry point by spawning Saproling tokens whenever its accumulated spore counters are spent, while Vorel of the Hull Clade works behind the scenes to double those very counters so you never run out of fuel. As long as your mana-producing creatures can foot the activation cost, every iteration feeds back into itself to generate infinite creature tokens, infinite life, and an endless cascade of untapped triggers.
