Sword of Light and Shadow can recur just with combat damage to a player
Similar to Porcelain Legionnaire in white, these are two cards that benefit from access to black mana, but that Im willing to put in the colorless section in a Cube because they dont necessitate access to much or any black mana: Dismember was just a game-changing card in Magic, and while Im more likely to use it as an answer to high-toughness creatures in my red decks or meaningful interaction in my green decks, its still high on my list of cards that I like to include in Cubes
Doomed Dissenter: pretty good replacement effect
This pairs excellently with Mahadi, Emporium Master, who produces a Treasure on your end step for each creature that died that turn, and with Prosper, Tome-Bound, who generates Treasures from impulse-drawn cards
Huge value potential here
It may seem strange to see so many of the original cards in this deck removed, including one of the deck's mascots, Kronk, Head of Security, but by focusing on Robin Hoods and Hyenas that either enable ping damage or benefit from it, we can find a clearer, more consistent strategy
