Mine Collapse turns Hexhaven Invigorator into a Valakut kill

A turn-four Modern line uses Mine Collapse on Hexhaven Invigorator to tutor Valakut, Roiling Canopy and Mountain–Forest lands, then converts repeated damage triggers into lethal landfall.

Source transparency: This Digest item is based primarily on reporting from MTG Rocks. TMF summarizes and interprets the news; original reporting remains credited and linked.
Hexhaven Invigorator gives Mine Collapse a new role in Modern: the free removal spell can target the player’s own creature and start a land-based kill. The core requires only Invigorator and Mine Collapse, although the battlefield must already contain at least two lands with both the Mountain and Forest types plus another Mountain available to sacrifice.

On turn four, Mine Collapse deals five damage to Invigorator. Its damage trigger then searches for five lands. The first package includes Valakut, the Molten Pinnacle, Roiling Canopy and three additional Mountain–Forest lands. Those entries generate three +3/+3 boosts through Canopy and three Valakut damage triggers. Pointing the boosts and, where necessary, the damage at Invigorator keeps it alive while causing further searches. Repeating the land packages produces additional Valakut triggers until the remaining damage can go to the opponent.

The line is complicated to execute but compact to include. Invigorator is a threat and land tutor outside the full combo, while Mine Collapse can still function as zero-mana interaction when sacrificing a Mountain is acceptable. Lightning Bolt offers redundancy as another way to damage Invigorator, though it does not replace every setup requirement.

Existing Valakut shells are the most natural home. Amulet Titan already plays land tutors and explosive mana, while Scapeshift strategies understand how to build around Mountain counts and Valakut thresholds. The package gives those decks a creature-based route that attacks from a different angle without abandoning their land engine.

There are meaningful weaknesses. Graveyard hate is irrelevant, but creature removal in response to the first trigger, land-hate effects, insufficient typed lands or a disrupted Valakut chain can end the attempt. The deck also has to balance color and land-type requirements carefully. No tournament result yet proves the package is established. Its current significance is that a newly printed card creates a plausible two-card Modern engine inside existing land-combo infrastructure.
