Block Cards

Utility cards with no stats, no arrows, and no cost. They occupy cells, obstruct arrows, and are the source of Color Synergy bonuses.

Properties (Set 00)

• No cost — you never pay credits to place a block.
• No arrows — blocks cannot trigger conflicts or activate abilities.
• No ATK / DEF stats — blocks cannot be involved in conflicts at all.
• Element — blocks do have an element (color). This matters for the Color Synergy rule.

How Blocks Enter the Board

Block cards are not played from hand in the normal sense. They enter the board only via the Block arrow ability: when a monster with a Block ability arrow points at an empty cell, you may place a Block card from your hand onto that cell.

Block cards must be in your hand to be placed. They enter as part of ability resolution — not as a separate action.

Blocks Do Not Score

Block cards do not count toward score, even when face-up in the main zone. Only face-up monster cards contribute to your point total.

However, blocks do occupy cells. When the last empty cell of the main zone is filled — by any card including a block — the game ends immediately. A block filling the final cell ends the game regardless of who placed it or what score either player has. See Scoring.

Color Synergy

Under the Color Synergy rule (currently Testing), a block card is an active support piece:

This makes block placement a strategic decision beyond cell occupancy — positioning a block of the right element next to your key monsters amplifies their stats in conflicts. See Color Synergy for full rules and examples.

Interactions

• Blocks can be removed by a monster using the Block ability arrow pointing at their cell. The removed block goes to the graveyard.
• Blocks in the out zone do not score and cannot trigger synergy with main zone cards, but can still be removed by the Block ability.
• Blocks cannot be targeted by Swap, Magnetism, Shockwave (push), or Resurrection. They are also immune to Firestorm and Remove — only the Block ability interacts with them directly.
• A Shockwave push can land on a cell occupied by a block, destroying the block (the pushed monster lands there).

Deck Building

There is no per-card copy limit on block cards. You may include as many block cards as you want in your 60-card deck. See Deck for full construction rules.

Block cards do occupy hand slots. Running many blocks means hands with less room for monsters — unless the Block ability can deploy them efficiently. This is a deck-building tradeoff.
