Tectonic HazardHow it works & interactions with other cards

What It Does

Tectonic Hazard is a targeted board clear that only affects your opponents and their creatures. When it resolves, it deals 1 damage to every opponent you are facing and 1 damage to every creature those specific opponents control. Importantly, this damage is dealt simultaneously to all affected targets, and it does not affect you or your own creatures.

Resolution Step-by-Step

First, you cast Tectonic Hazard by paying one red mana. Upon resolution, the game checks who your opponents are and what creatures they currently control. The spell then deals 1 damage to each of those players and 1 damage to each of their creatures. If a creature has 1 toughness and no shield or damage-prevention effects, it will be destroyed as a state-based action immediately after the spell finishes resolving.

Common Mistakes

One common mistake is assuming Tectonic Hazard hits Planeswalkers or Battles; the Oracle text specifies only 'opponent' and 'creature'. Another error is forgetting that this spell does not target. Because it says 'each', it bypasses keywords like Hexproof or Shroud on creatures, though it will still be prevented by protection from red or effects that prevent noncombat damage.

When to Play It

This card is best utilized against 'go-wide' strategies, such as decks relying on 1/1 Elf or Goblin tokens. It is also a cheap way to trigger abilities that care about noncreature spells being cast or to chip away at an opponent's life total when they are at a critical threshold.

Interaction examples

Clearing the Board

If your opponent has three 1/1 creature tokens, casting Tectonic Hazard will deal 1 damage to each token and 1 damage to the opponent. All three tokens will be put into the graveyard simultaneously after the spell resolves.

Faithless Looting

If you are facing an army of small creatures but don't have Tectonic Hazard in hand, you can cast Faithless Looting to draw two cards. If you draw Tectonic Hazard, you can then cast it for its mana cost to clear the opponent's board, effectively using the loot to find your specific solution.

Total Destruction

Vandalblast

Against a player with both small creatures and artifacts, you can cast Vandalblast for its Overload cost to destroy all artifacts they control, then follow up with Tectonic Hazard to wipe out their 1-toughness creatures, leaving their side of the battlefield completely empty.
