Perilous Forays + Eusocial Engineering + Horizon Explorer

Perilous Forays

Eusocial Engineering

Horizon Explorer

How it works

1. Activate Perilous Forays by paying 1 and sacrificing a creature you control, searching your library for a land card with a basic land type and putting it on the battlefield untapped due to Horizon Explorer.
2. When the land enters the battlefield, Eusocial Engineering triggers, creating a creature token.
3. Activate the land by tapping it, adding 1.
4. Repeat.

This clever loops relies on Horizon Explorer to ensure that every land fetched by Perilous Forays enters the battlefield untapped, providing the mana needed to keep paying for its activation. As each land arrives, Eusocial Engineering triggers to instantly replace your sacrificed creature with a fresh 2/2 Robot token, fueling the engine indefinitely. Through this continuous cycle, you are able to rapidly thin your deck and pull every single land with a basic land type directly onto the battlefield.
