I believe setting thresholds and knowing what to pull will improve your efficiency and profitability
if you make 20 Tokens from an Ancient Copper Dragon or Mahadi, that is a massive amount of damage being thrown at peoples faces
While in RTR the truly awful cards were Aquus Steed, Chronic Flooding, Destroy the Evidence, Drainpipe Vermin, Shrieking Affliction, Sphere of Safety, Survey the Wreckage, Oak Street Innkeeper, and Urban Burgeoning, with only five of those at common, GTC presents us such gems as Hydroform, Primal Visitation, Guildscorn Ward, Contaminated Ground, Dying Wish, Illness in the Ranks, Mental Vapors, Crackling Perimeter, Structural Collapse, Tin Street Market, Furious Resistance (no, it is not a red Smite, people!), Alpha Authority, Predator's Rapport, Serene Remembrance, Coerced Confession, and Skyblinder Staff
If I somehow missed your favorite card, I hope youll let me know in the comments
Psychic Frog is different, and its a decent madness enabler
