Wave Crush

Wave Crush (；nami-funsai) is a keyword introduced in BS66, exclusive to Petit Shack. The wording is as follows:
* / [LV1][LV2] (When Attacks)Banish a card from the opposing decktop. For each 4 cost this Spirit has, this effect banishes +1 card. Also, this Spirit's symbol is fixed as zero. 
As the name implies, it is a new variant of , with some similarities and also some major changes. Like , it looks at the spec of the card with the keyword; But instead of level, it looks at the cost. And while it is named after "Crush", it isn't actually a deck-discarding effect, but a deck-banishing effect. On top of that, the effect also removes the symbol of the attacking Spirit, allowing the user to focus purely on attacking the opponent's deck, not giving the opponent extra resources in the process. 
Being a banish effect, the merit includes bypassing all existing anti-mill effects (e.g. Gardenia Field), and removing opponent's cards without needing to worry about how sending cards to Trash might help the opponent instead when they are using decks with strong trash retrieval and reanimation power. Fixing own symbol as zero, as mentioned, allows the player to attack without reducing the opposing Life, which stops the opponent from gaining core resources through taking lives, or using any cards with effects that activate when their Life is reduced/activate Bursts that reacts to Life reduction (e.g. Magibullet, Burst Wall (Revival), The Phanto-Magia Hermit-Ritter Badgerdulles etc.) 
As a new keyword, the demerit includes how it can't be supported by effects that support alone in the past. Effects that increase the amount of cards to be banished are also very rare when compared to normal mill. When effectiveness are to be considered, with the initial amount being "one", the increase per four cost is relatively tame. However, being the center of the Wave Contract deck, new cards introduced in the same set have more or less covered the weakness. And as a keyword that is printed on a Contract Spirit which revolves around Brave, it also means that it can be activated consistently with bringing back the card, and Braves raising the cost to a considerable amount (e.g. Cost 8 Advent + Cost 4 Brave = Banish 5 cards at once).
