OPERATIONAL
The intelligence operator
inside the lab.
RIKA is HZOV4's operational intelligence assistant. She connects the Companion, Discord and ranked evidence so every test becomes structured knowledge instead of a forgotten result.

& Knowledge Assistant
& Knowledge Assistant
Not a generic chatbot. RIKA is built around one specific competitive workflow: study, test, record, compare and improve.
PRIVATE COMPETITIVE INTELLIGENCEWhat RIKA does today.
Turns logs into signals.
Aggregate wins, losses, play order and matchup records move from the Companion database into Discord automatically.
Routes matchup knowledge.
RIKA gives members fast access to matchup briefs, current deck spaces and the full decision maps stored in the Companion.
Keeps the loop moving.
Ranked footage, testing discussion and personal logs remain connected instead of becoming separate archives.
Evidence moves. Knowledge compounds.

Automation and intelligence routing

TRUST LAYER
Useful because she knows her limits.
- RIKA never exposes private notes or account specific testing logs.
- She reports recorded evidence and does not invent competitive conclusions.
- The current system is structured automation. Adaptive AI assistance will expand only where it improves the testing loop.

Valerio “HZOV4”
I am Valerio, better known as HZOV4. I am from Rome and I have been playing One Piece Card Game since OP02.
I like decks that reward planning, matchup knowledge and small decisions made well. My routine is simple: study the theory, play a lot of ranked games, take notes and keep improving the list.
BY Luffy has been my favourite deck. Nami is the deck I have brought to events most often lately, but now I am fully committing to RG Luffy for OP16.5.
Current focusRG LuffyFavourite deckBY LuffyRecent eventsUY Nami

STILL GRINDING
It is not much, but it is what it is. Three Top 64 finishes are a decent start, never the destination. I am honest about where I am, and I am aiming much higher.

Back to back.
Two Serial Yamato wins.
The second title ended with a Nami mirror. I brought Sky Island because it gave me the tools I wanted for that exact fight.
5c Luffy kept the pressure high. Eight total copies of 7c Robin made the mirror much more consistent.Original result post ↗

OP16.5 LIST UPDATE · 11 AUG 2026Four Nika buildOPEN THEORY NOTE
−41c Bonney+37c Nika+16c Brook
Current core: 0 Bonney · 4 Nika · 4 Brook.
Mirror and Mihawk demand more Nika.
7c Nika is a premium answer in the RG mirror and against Mihawk builds using 7c Shanks and 9c Mihawk. Hard drawing four Nika and four Brook is worth more than spending early DON!! on Bonney searches.
Stay at four life.
Nika leaves the leader at a 5k base for the turn. Preserve every early life so repeated Nika hands remain playable and the opponent cannot force you away from the Nika line.
Spend less DON!! searching.
Minimise early searches and leave maximum DON!! active to protect life. 1c Nami remains worthwhile because she improves Nika; 1c Bonney is usually too expensive unless the curve is missing.
