What do the attacks on Magikarp & Wailord-GX SM166 cost, and what do they hit for?
The card prints 2 attacks. The strongest asks for 5 Energy and returns 180 damage, which is 36 damage for every Energy card attached.
| Attack | Energy cost | Cards of Energy | Printed damage | Damage per Energy | Effect |
|---|---|---|---|---|---|
| Super Splash | 5 Water | 5 | 180 | 36 | No extra effect. |
| Towering Splash-GX | 1 Water | 1 | 10 | 10 | If this Pokémon has at least 7 extra Water Energy attached to it (in addition to this attack's cost), this attack does 100 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) (You can't use more than 1 GX attack in a game.) |
Retreating costs a further 4 Energy, discarded from this card, and that cost is paid on top of anything in the table.
What each attack asks a deck to attach before it can be used, drawn as the symbols printed on the card.
One Energy card attaches per turn, so the number of symbols is also the number of turns the attack waits.

Back to summaryIs Magikarp & Wailord-GX SM166 efficient for the Energy it asks for?
Printed damage on its own says nothing — a 180 damage attack that needs 5 Energy and one that needs two are different cards. Dividing one by the other puts every attack on the same scale.
Each bar is what cards asking that much Energy typically print, divided by the Energy they ask for. The number beside the bar is that figure.
Cards whose cheapest attack costs 1 typically return 49.0 damage per Energy card. This card returns 36.

Further right is a costlier attack, further up is a harder-hitting one, so the cheap and heavy corner is top left. The size of a grey dot is how many cards sit at that Energy cost.

Where this sits once the archive is cut by damage instead
The bars above cut the archive by what an attack asks for. Cut the same archive by what an attack prints and the groups come out differently — the damage ranges on record are gathered on one page, which is where a figure like 180 is read as high or low rather than merely large.
Is Magikarp & Wailord-GX SM166 strong for a TAG TEAM card?
TAG TEAM cards are built large to begin with, so measuring this one against the whole archive mixes up what the mechanic gives it with what the card itself gives it. Measured inside its own group, the two come apart.
The group is every TAG TEAM card in the archive — 130 of them. Each figure is compared with what that group typically prints, not with the archive as a whole.
What does being a Water card do for Magikarp & Wailord-GX SM166?
Type decides two things at once — which cards take double damage from this one, and which cards deal double to it. Both are read from the weakness printed on each group, not from a rule of thumb.
17,249 cards carry an energy type. The note under each name is the weakness printed most often on that group.

| Fairy | 1.4% | 237 cards |
Read from the weakness printed on each group. The first row is this card; the rest are groups that most often print a Water weakness.
What being a Water card is worth
Groups that most often print a Water weakness: Fire (1,574 cards). Against those, this card's printed damage counts double. Going the other way, Water cards are themselves most exposed to Grass.
What knocks out Magikarp & Wailord-GX SM166 in one hit, and what does it knock out?
Weakness doubles the damage a Grass attack deals to this card, so the bar it has to clear is 150 printed damage rather than 300.

Magikarp & Wailord-GX SM166300 HPWhy this card was picked to stand opposite
Of the 116 cards in the archive that can remove Magikarp & Wailord-GX SM166 in a single attack, this one clears the bar by the smallest margin — 150 printed damage against a bar of 150. Anything printed higher removes it just as surely, so this is where the line actually sits, and this print is legal in Standard play today.

300 HP against a Grass ×2 weakness means any Grass attack printed at 150 damage or more is enough. 116 cards in the archive clear that bar.

Which rules apply to Magikarp & Wailord-GX SM166, and where can it be played?
Two kinds of rule meet on one card — the sentence printed on the card face, and the rulebook clauses that apply because of what the card carries.
The rule printed on this card
“TAG TEAM rule: When your TAG TEAM is Knocked Out, your opponent takes 3 Prize cards.”
Prize cards your opponent takes when it is knocked out
Every knockout carries the opponent 3 steps closer to winning, and that is the cost of putting this card on the field whatever it cost to buy.
| Clause | What the rulebook says | Cards it applies to | Share of the archive |
|---|---|---|---|
| Weakness | Some Pokemon have Weakness or Resistance to Pokemon of certain types, marked in the lower-left corner of the card. | 16,744 cards | 81.9% |
| Retreat | Retreat your Active Pokemon (only once per turn). | 17,244 cards | 84.3% |
| Energy per turn | You can attach Energy just once each turn! | 17,180 cards | 84.0% |
Counted across 20,444 English cards. A clause applies to this card because the card carries the property the clause names, not because we judged it to.

Magikarp & Wailord-GX SM166 in depth — what these figures add up to
Three readings of the same card, side by side: what it costs to get going, where it sits among the cards it will be compared with, and what takes it off the field.
What it asks a deck for
- Its hardest attack, Super Splash, needs 5 Energy attached. Energy attaches once a turn, so that attack waits 5 turns from an empty card.
- That works out at 36 damage for every Energy card attached.
- Moving it out of the active spot costs 4 more Energy, discarded from the card itself.
Where its HP stands, cut four ways
What actually removes it
- A Grass attack printed at 150 damage removes it in a single turn — that is the bar, not its 300 HP.
- 116 cards in the archive clear that bar.
- Going the other way, it removes 1,700 cards in one attack.
