Beckett Mariner, Impetuous Ensign

A 2/1 first striker is far below Badgermole Cub's 49-level two-drop baseline, and three taps for 2 face damage is too slow for listed decks.

Could be wrong if An unrevealed efficient tap/untap or Vehicle-style shell could make the promotion trigger materially more reliable.

It cannot realistically compete with Emberheart Challenger (77) in red aggro; attacking three times for a single 2-damage payout is poor rate.

Could be wrong if A dedicated repeatable-tapping engine could provide a niche that ordinary aggro lists do not.

Modern's aggressive creatures need immediate value or exceptional rate; this is dramatically weaker than Ragavan (83) and has no credible listed shell.

Could be wrong if A low-cost tap/untap combo that uses the damage as a win condition could create a narrow application.

A vulnerable 2/1 that needs three taps for 2 damage lacks Legacy-rate impact and does not offer the unique disruption of Orcish Bowmasters (94).

Could be wrong if A presently unaccounted-for repeatable untap loop could make it a compact damage outlet.

Multiplayer makes each third tap worth 6 total damage, but the fragile body and slow setup leave it a narrow, replaceable tap-synergy payoff.

Could be wrong if Reliable untap engines or commander-specific tap support could make repeated promotion cycles much stronger than expected.

A two-mana 2/1 first striker attacks and blocks well early; the eventual 2 damage is useful race pressure but not a major payoff.

Could be wrong if Unknown speed, creature sizing, and removal density could shift first strike from valuable combat leverage to mediocre filler.
