Notes & Combos

Reached Master 1 using my the same decklist I used to reach Master 5. The climb overall was smooth, better experience compared to Duelist Cup's Stage 2 grind.

Gameplan remains the same, and the banlist really helps in easing the ladder grind for this deck.

Losses are mostly against Mitsu/Ryzeal decks and their variants. Similar to Duelist Cup, but somehow it is not that prevalent in the ladder.

Matchups against Odion decks can be quite challenging. You have to know what cards to use for baiting the Apophis traps. The hardest Odion matchups are against the counter trap variants.
