The Commander

Flying

If a creature you control that entered this turn would deal damage, it deals twice that much damage instead.

Guide

Gameplan

Flood the board with hasty or freshly-arrived creatures and turn their first hit into a death blow — Neriv doubles all combat and noncombat damage from creatures that entered the battlefield this turn. You go wide and fast in Mardu colors, leveraging haste enablers, blink/flicker, and ETB or attack-trigger damage to burst opponents down before they stabilize.

Strengths

Doubles damage from any creature that entered this turn, including big hasty attackers and damage-dealing ETBs
Mardu colors give access to the best removal, haste enablers, and aggressive token makers
Rewards blink and recursion loops since 're-entering' creatures qualify each turn
Can pressure all three opponents quickly and close games out of nowhere

Weaknesses

The doubling only applies to creatures that entered this turn, so static board presence gives no benefit
Highly creature-dependent, so wraths and spot removal hit you hard
Neriv himself is a 4-mana enabler that does little the turn he's cast without haste
No card advantage engine built in — can run out of gas after a board wipe

Key Cards

Fervor — Gives all your creatures haste so they can attack the turn they enter and trigger Neriv's doubling immediately.
Hellrider — Each attacking creature pings for 1, doubled to 2 by Neriv, turning a wide swing into massive reach damage.
Purphoros, God of the Forge — Every creature ETB deals 2, doubled to 4, making token floods lethal across the table.
Terror of the Peaks — Deals damage equal to power when other creatures enter; doubled by Neriv it becomes a removal and burn engine.
Combat Celebrant — Its exert grants an extra combat with freshly-entered attackers still doubled, enabling huge alpha strikes.
Conqueror's Flail — Protects your aggressive turns from instant-speed interaction that would blow out a doubled swing.

Upgrade Path

Add more reliable haste (Hammer of Purphoros, Anger, Hall of the Bandit Lord) and extra-combat effects (Aggravated Assault, Aurelia) to maximize doubled swings. Lean into recursion and protection — Boros Charm, Heroic Intervention, and a few blink outlets like Conjurer's Closet keep your enablers entering each turn. Tighten the mana base with fast lands and rocks so Neriv plus a haste enabler can land early and end games fast.

Archetypes

Aggro Tokens — Go wide with hasty tokens and double their combat damage for explosive board-based kills.
Blink — Flickering creatures makes them 'enter this turn' repeatedly, doubling their ETB and combat damage every loop.
Burn/Spellslinger — ETB damage creatures and pingers like Purphoros and Terror of the Peaks have their damage doubled into a burn finish.
Reanimator — Reanimated bombs entered this turn, so cheating in a big haste threat doubles its damage output.
