Beckett Mariner, Impetuous Ensign
Repeatedly tap and untap Beckett Mariner using Vehicles, tap-for-mana rocks, and untap artifacts to trigger her Reckless Behavior ability as fast as possible. Damage-amplifying permanents like Torbran, Solphim, and Ojer Axonil multiply the damage to burn opponents out rapidly.

Deck anatomy
What this list actually runs on: how cheaply it casts things, and whether it has enough ramp, card draw and interaction to keep up at the table. Each block is one card — hover for its name.

The working parts
Counted from Scryfall’s community card tags, not from the builder’s own labels. A card that does two jobs counts twice, so these add up to more than the deck. The hatched band is a common rule of thumb, not a law — combo decks run leaner, battlecruiser decks heavier.
