Dauntless Onslaught: A Versatile and Powerful Spell in Modern Magic

TL;DR Summary

Dauntless Onslaught is an instant spell that grants a boost to the power and toughness of two target creatures, making them more formidable on the battlefield. Its versatility and ease of use make it a staple in many Magic: The Gathering decks.

Detailed Card Mechanics and Interactions

As an instant spell, Dauntless Onslaught resolves immediately after being cast, allowing it to interact with other spells and abilities as they resolve. When casting Dauntless Onslaught, the player targets two creatures, which are then granted a +2/+2 boost until the end of the turn.

This boost is applied in parallel, meaning that if both targeted creatures are given the same amount of power and toughness, their total boost will be doubled. For example, if Dauntless Onslaught is cast on Angelic Procession and Giant Growth, the former gains +4/+4 while the latter gains +4/+4.

Dauntless Onslaught also has an interesting interaction with other spells that modify creature power or toughness. For instance, if a player uses Chandra's Phoenix to give a target creature +3/+3 for its controller's next turn, Dauntless Onslaught can further enhance the boosted creature by granting it another +2/+2.

Strategic Uses, Combos, and Synergies

Dauntless Onslaught is most effective when used in conjunction with other creatures that benefit from increased power or toughness. Some popular combinations include:

  • Token Generation: Dauntless Onslaught can be used to accelerate the growth of token creatures, allowing them to deal more damage on the battlefield.
  • Aggro Strategies: By granting a large amount of power and toughness to small creatures, Dauntless Onslaught can help fuel aggressive decks that rely on quick kills.

In terms of specific card synergies, Dauntless Onslaught pairs well with cards that benefit from increased creature power or toughness, such as:

  • Chandra's Phoenix: This can help accelerate the growth of creatures like Elvish Mystic or Monastery Swiftspear.
  • Fate Reaver: By granting a large amount of power and toughness to a target creature, Dauntless Onslaught can make Fate Reaver's ability more impactful.
  • Luminarch Aspirant: This can help create an unstoppable force on the battlefield by buffing up Luminarch Aspirant with Dauntless Onslaught.

Deckbuilding Roles and Archetypes

Dauntless Onslaught is often included in decks that focus on creature-based strategies, particularly those that rely on token generation or aggressive play. Some deck archetypes that make use of Dauntless Onslaught include:

  • Token Decks: By granting a large amount of power and toughness to small creatures, Dauntless Onslaught can help accelerate the growth of tokens.

Format Viability and Competitive Context

Dauntless Onslaught has seen various degrees of success across different Magic: The Gathering formats. In standard play, this instant spell is generally considered too weak to be competitive at the top level, but it can still find success in casual or constructed formats where more powerful spells are not available.

  • Card Advantage: Dauntless Onslaught is considered a "card draw" spell, as it resolves immediately after being cast. This allows it to take effect before many other spells or abilities can resolve.
  • Stacking: When casting Dauntless Onslaught, the player targets two creatures that are already on the stack. If these creatures have any effects that modify their power or toughness, they will be resolved first and then Dauntless Onslaught takes its effect.
