Attacker

Strategy & play

How Rillaboom plays — derived from its stats and the rules of the game, not an opinion.

Its main attack (Raging Repeated Strike) needs 3 Energy — a turn-3 swing on manual attachment — you’ll want Energy acceleration to power it up on time.
Hits for 120 — one-shots small Basics and support Pokémon, but trades down into the format’s big attackers.
Needs Grass Energy to attack — your line must supply that color.
Grass type, weak to Fire ×2 — a Fire attacker doing ≥90 effectively one-shots it.
A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
Retreat cost 3 — gets stranded Active if gusted; run Switch / Escape Rope or a Float Stone-style Tool.

How to beat Rillaboom

Exploit its Fire weakness — ≥90 damage one-shots it.
Gust it before the evolution is set up.
Trap it Active — 3 retreat means it can’t escape without help.

For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
