Fertilid + Lotus Cobra + Archelos, Lagoon Mystic + Thranduil's Company

Fertilid

Lotus Cobra

Archelos, Lagoon Mystic

Thranduil's Company

How it works

1. Activate Fertilid by paying 1 and removing a +1/+1 counter from it, causing you to search your library for a basic land card and put it on the battlefield untapped due to Archelos.
2. When the basic land enters, Lotus Cobra and Thranduil's Company trigger.
3. Resolve the Lotus Cobra trigger, adding .
4. Resolve the Thranduil's Company trigger, putting two +1/+1 counters on Fertilid.
5. Activate the basic land by tapping it, adding 1.
6. Repeat.

This clever engine turns Fertilid into a self-sustaining land-tutor by leveraging multiple overlapping permanents to keep the cycle going. With Archelos, Lagoon Mystic positioned in its tapped state, every land fetched by Fertilid immediately enters the battlefield untapped instead of tapped, which in turn triggers Lotus Cobra to refund the green mana required for the activation. Meanwhile, Thranduil's Company provides the crucial +1/+1 counters needed to replenish Fertilid's ammunition every time a land drops, ensuring you can strip-mine your entire library for basics in one glorious loop.
