Strategy & play

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

A Basic — hits the board turn 1 with no evolution tax.
Inflicts Poison — guaranteed chip damage every turn between turns (no coin flip). It stacks with your attack math to cross KO thresholds the attack alone misses.
Needs Grass Energy to attack — your line must supply that color.
Grass type, weak to Psychic ×2 — a Psychic attacker doing ≥35 effectively one-shots it.
A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
Seen in 0% of recent tournament decks that can run it, usually 1 copy.

How to beat Seviper

Exploit its Psychic weakness — ≥35 damage one-shots it.
On the receiving end of a condition? Retreat, switch, or evolve to wipe it — conditions only stick to the Active.

Frequently asked

How can I tell if my Seviper is real?

Seviper is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the back-light test (real cards have a black inner layer that blocks light; counterfeits glow through), the rosette dot pattern on the back under magnification, font weight and kerning on the card name, and the holofoil pattern if applicable. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
