Diego Cassiraga vs Stephane Ivanoff: Match Analysis

This semifinal featured a direct clash between Diego Cassiraga’s Pikachu & Zekrom-GX strategy and Stephane Ivanoff’s Zoroark-GX-based deck. The match demonstrated how sharply a Pokémon Trading Card Game series can change from one game to the next. Early setup, Ability access, Energy acceleration, and gust effects all played major roles.

The matchup ended with Stephane advancing after winning two games. Diego’s strongest moments came when he established an early prize lead in the second game and created pressure around Pikachu & Zekrom-GX. Stephane’s advantage came from turning Zoroark-GX into both a draw engine and an efficient attacker.

Video Highlights:

• Stephane establishes multiple Zoroark-GX and uses Trade to build a large hand.
• Alolan Muk limits Diego’s access to basic Pokémon Abilities.
• Diego uses Pikachu & Zekrom-GX and Energy Switch to create a comeback position.
• A double-prize penalty changes the number of prizes Diego needs in game three.
• Stephane closes the match by managing Persian-GX, Acerola, and gust effects.

Game one quickly became a lesson in tempo. Diego attached Energy and passed without playing a Supporter, while Stephane immediately developed Zorua, Ditto Prism Star, and multiple Zoroark-GX. Once several Zoroark-GX entered play, Trade allowed Stephane to discard unnecessary cards and draw toward the exact resources required for each turn.

Zoroark-GX did not need to take enormous one-hit knockouts to control the game. Its value came from combining consistent draw with Riotous Beating. That combination allowed Stephane to maintain a full hand while applying steady pressure to large Pokémon-GX targets.

The most important defensive card was Alolan Muk. Its Power of Alchemy Ability turned off the Abilities of Basic Pokémon, affecting several parts of Diego’s setup. Jirachi could no longer provide Stellar Wish, and Tapu Koko Prism Star could not provide its usual Energy acceleration. The lock also made Marsh Shadow less useful for Diego.

Stephane also used Guzma to bring targets into the Active Spot at favorable times. Instead of allowing Diego to stabilize, he attacked the Pokémon that best supported the opposing board. A damaged or stranded Pokémon could become a liability when Diego lacked a switching card.

Diego eventually used Tag Bolt-GX to take a knockout, but the prize cards did not provide the resources needed to continue attacking. With Thunder Mountain Prism Star unavailable and Alolan Muk still limiting Abilities, Stephane remained ahead. Riotous Beating then removed Pikachu & Zekrom-GX for three prizes, placing the game beyond Diego’s practical recovery range.

Game two developed differently. Diego opened with a more active board and began taking prizes from Stephane’s smaller Pokémon. The early targets included Pokémon such as Meowth and Tapu Lele-GX, allowing Diego to create a lead before Stephane could fully establish multiple Zoroark-GX.

Stephane’s opening was unusually restrained. He had access to some useful cards but struggled to assemble the complete chain of Zoroark-GX, Trade, and draw effects. Judge refreshed both hands at one point, but the result still left Stephane searching for a stable engine.

Diego’s most effective plan was to avoid giving Stephane time to build freely. Instead of focusing only on the largest target, he used Guzma to target vulnerable Pokémon and increased his prize advantage one knockout at a time.

The turning point came when Diego used Energy Switch and Energy acceleration to prepare Pikachu & Zekrom-GX. He did not need a perfect opening hand; he needed enough pieces to convert his existing board into a meaningful attack. This was a strong example of using limited resources to preserve the prize race.

Stephane tried to regain momentum with Zoroark-GX and later considered Persian-GX as an additional attacker. However, Diego’s lead meant that every knockout had to be evaluated carefully. A large knockout could provide Stephane with a route back into the game, while a small knockout might not produce enough tempo.

Diego ultimately tied the series. The game showed the value of acting before the opposing draw engine became fully operational. Even though Stephane eventually found stronger cards, Diego had already converted his early turns into a lead that could not be easily erased.

The deciding game contained the most complicated sequence of the match. Diego again faced an awkward opening hand and used Marsh Shadow’s Let Loose to reset both players to four cards. This was a risky decision because Let Loose can also reduce the user’s own access to resources, but Diego needed a way to change the game’s direction.

After the reset, Diego found a Supporter and used Dedenne-GX to refresh his hand. He also placed Thunder Mountain Prism Star into play, preserving the possibility of an accelerated Pikachu & Zekrom-GX attack. Stephane, meanwhile, developed Zoroark-GX and searched for Alolan Muk.

A judge ruling then became part of the game. After an accidental extra-card situation was reviewed, Stephane received a double-prize penalty. This changed Diego’s win condition: instead of taking six prizes, he needed to take four. The penalty did not remove Stephane’s board advantage, but it made each future knockout more important.

Stephane’s response was disciplined. Rather than rushing into an unfavorable exchange, he continued using Trade and searched for ways to protect damaged Pokémon. Acerola became especially important because it removed damage from Zoroark-GX and effectively denied Diego a knockout.

Stephane also used Guzma to bring forward Diego’s most relevant targets. The goal was not simply to take prizes immediately. It was to force Diego to spend Energy, switching cards, and Supporters while Stephane preserved a route to the final prize.

Persian-GX created an additional threat. If Diego knocked out one of Stephane’s Pokémon-GX, Persian-GX could potentially use its attack based on Pokémon in the discard pile. This forced Diego to consider whether a knockout was actually safe. The double-prize penalty narrowed the required prize count, but it did not eliminate the need for precise target selection.

The final turns showed how difficult it is to win from a low-resource position. Diego used Dedenne-GX to draw six new cards and then tried to improve his chances with Jirachi’s Stellar Wish. He needed Guzma to reach the correct target, but neither the new hand nor Stellar Wish provided it. Stephane then completed the series and advanced to the final.

This match is useful beyond the specific decks involved because it highlights several transferable Pokémon TCG principles. First, setup quality often matters more than the theoretical strength of a matchup. Stephane’s Zoroark-GX deck looked dominant when Trade was active, but Diego’s pressure in game two demonstrated how vulnerable that engine could be before it developed.

Second, Ability denial can reshape an entire strategy. Alolan Muk did not attack for the most damage, yet its presence affected Jirachi, Tapu Koko Prism Star, and Marsh Shadow. When building or piloting a deck with several Basic Pokémon Abilities, always identify which opposing cards can disable them.

Third, prize mapping must include future turns. Stephane’s use of Guzma, Acerola, and Persian-GX showed that a current knockout may create an unfavorable board for the next exchange. Diego’s best turns came when he planned Energy placement and switching options together rather than treating each attack as an isolated action.
