Grimlock, Dinobot Leader // Grimlock, Ferocious KingHow it works & interactions with other cards

Dual Modes and Static Buffs

In his front-face mode, Grimlock, Dinobot Leader, provides a static +2/+0 power boost to three specific groups: Dinosaurs, Vehicles, and other Transformers creatures you control. This makes even small utility creatures significantly more threatening. On his back-face mode, Grimlock, Ferocious King, loses the static anthem but gains Trample, turning himself into a lethal attacker with 4/5 stats.

The Conversion Process

Grimlock features a unique activation cost: {2} mana and the physical act of converting a Transformers toy you own. To resolve this, you must physically change the toy's mode (e.g., from robot to vehicle). Once the cost is paid and the ability resolves, Grimlock flips to his other side. Note that Grimlock himself does not have the 'Convert' keyword; he simply 'becomes' the other side upon resolution.

Common Mistakes

A common error is assuming Grimlock's power boost applies to himself while he is in his 'Dinobot Leader' form; however, the text specifies 'other Transformers creatures,' so he does not buff his own power. Additionally, remember that while he is an Artifact Creature on both sides, he only counts as a Dinosaur on his back face. If you do not own a physical Transformers toy to convert, you cannot activate his transformation ability.

Interaction examples

Strategic Transformation

Solemn Simulacrum

With Grimlock, Dinobot Leader on the battlefield, you cast Solemn Simulacrum. While Solemn Simulacrum is an artifact creature, it is not a Dinosaur, Vehicle, or Transformer, so it remains a 2/2. However, if you had a Vehicle like a Smuggler's Copter, Grimlock would increase its power. You can use your turn to develop your board with the Simulacrum's land-search ability, then pay {2} and convert a toy to turn Grimlock into his Ferocious King mode to prepare for a trample attack on the following turn.

Recovering the Leader

Eternal Witness

If Grimlock is destroyed and sent to the graveyard, you can cast Eternal Witness to return him to your hand. When you cast Grimlock again, he always enters the battlefield on his front face, Grimlock, Dinobot Leader. This allows you to immediately regain the +2/+0 anthem for your other eligible creatures on the board.
