Caverns of Despair One doesnt usually associate red with cards that slow down the game
A deck focused on token generation and sacrifice effects, such as a Black/White Aristocrats or a Black/Green Sacrifice deck, would benefit from including Mirkwood Bats in its strategy
On top of that, the fun police pairing of Teferi, Time Raveler and Oko, Thief of Crowns respectively stop Marvel from functioning or turn a Marvel that failed to hit something good on its first spin into an Elk
If you own a Smothering Tithe or Dockside Extortionist, you know what they can do in a four-player pod, but we can also point to all-stars like Teferis Protection, Esper Sentinel, and Akromas Will in white, and for red theres Jeskas Will, Underworld Breach, and Terror of the Peaks
Card drawing is good, and no cards do it better than Greater Good, Harmonize, and Momentous Fall
