As risky as it might sound, many decks cant answer a big indestructible 5/5 flier, so it can be an interesting card coming out of the sideboard
Dont overload the rules text If your custom card needs 11 lines of text, consider one of these options: tighten wording use existing keyword phrasing where it makes sense split it into two cards accept that you are making a commander that is also a short story Keep readability as the goal Custom cards live on a table, not in a zoomed-in screenshot
I also prepared for the mirror by only running two field spells, because a) I didn't want to set up field spells on the chance that my opponent got Balerdroch in the GY and I didn't have an answer to it b) If I ever needed field spells, I could either search Vampire Kingdom with Vampire Takeover or Vampire Retainer or let my opponent activate a field spell instead, while allowing myself to use that deck space on more useful cards
Get this on the field, and you can discard a card to Special Summon a Knightmare from the deck
Will be at the Tokyo area
