Octillery (PL 58). Octillery's "Water Vein" attack is not working correctly. I reveal 3, 4, or 5 Energy cards, yet the coin flips consistently come up tails. It happened to me four times in a row that I revealed 3 Energy cards, and on all four occasions, all three flips resulted in tails. I strongly request a review of the attack's programming; I suspect there may be a "nerf" specifically affecting the coin flips for this attack—perhaps an adjustment or intervention in the `math.random()` function—to reduce its effectiveness. At the very least, I would like a response confirming whether the attack was nerfed via a code change specific to it, so I can decide not to play with this card again.

Triage: doesn’t look like a bug or intentional nerf to me.

Your logs show Water Vein used twice during this game. The second use did not get TTT.

The code in tcgone-engine-contrib seems to use the shared flip mechanism that is common to other cards with flip effects.

onAttack {
   flip my.deck.subList(0,5).showToMe("Top 5 cards of your deck").showToOpponent("Top 5 cards of your opponent's deck").filterByType(ENERGY).size(), {
      damage 50
   }
   shuffleDeck()
}

(note 1: it has happened before that the live server uses a different version of the code for some cards that may not be the same as withat is in tcgone-engine-contrib.)

(note 2: I do not have access to the engine code and do not speak for TCG ONE. This is just my assessment based on the log evidence, public card code, and some testing through devui.)
