What is locked, what the real flex slots are, and four changes worth testing one at a time.
4 cards sit outside the curve: the Battlefield and the Legend are played from their own zones and have no Energy cost.
Card types
40 cards in the main deck. The Battlefield and Legend play from their own zones and are not counted.
Power by domain
16 of 44 listed cards carry a Power requirement. A card with two domains counts under both, so these do not sum to the deck size.
Energy, type and domain are printed card values from the Riftcodex snapshot, joined against this guide’s list.

Already the recommended change: one out, one in. It improves Master Yi with Hourglass, Irelia Gear, Draven, Azir, LeBlanc Hook, Aurora decks and Equipment engines generally. It worsens damage-heavy Kennen, damage-heavy , Ezreal builds based on direct spell damage, and mirrors where matters.
The next card I would want. It improves Kennen, Ezreal, , LeBlanc, Irelia and Gear or spell-engine decks generally, and the likely cut is the remaining . Make that change only when damage prevention has few expected targets.
Two out, two Rampage in. Another successful build ran Rampage main and shifted to an eight Body and four Fury rune configuration.◆src
It improves tall units, combat-centric midrange, situations where your own large unit clears several bodies, and Body Power consistency. It worsens split damage across two small units, damage outside combat, finishing damaged units at different locations, and some Ambush and token matchups.
Two out, two Grim Apothecary in. Apothecary has Ambush and can return a friendly battlefield unit to hand when played, and it appears heavily in both older and current successful configurations.◆src
It improves reactive deployment, protection from removal, reuse of , Kinkou, or Brynhir, and -style replay without depending on the battlefield. It worsens ready chains, multi-action offensive turns, and total board count. This is the first unit swap worth testing once the source build feels comfortable.
Better against Ezreal, , LeBlanc, Nasus and long games where an extra card beats an anti-tall combat effect. Worse against Master Yi, Irelia, single-defender decks generally, and it gives up the Trophy Hunter lane-breaking line entirely. This is a metagame choice, not an upgrade.◆src
In a removal-heavy or highly reactive field, two out and two in. It improves hidden-information pressure, Ganking, midgame topdecks and resilience to being stranded. It worsens one-Energy openings, early Kinkou support, enablement and Legion sequencing. Keep Pyke in the sideboard until the field is genuinely slow.
