As a simple example, until someone finds a checklist or similar for Ice Age development, I cannot be fully sure that a Sphere of Annihilation version wasn't playtested for Ice Age in 1992, and my collection of pre-Alpha Orbs may well be incomplete without me knowing it
Thanks to the Most Wanted Commander Deck, Outlaws go hand in hand with Treasure generation, and Prosper is one of the best of the bunch in that area
This creature punishes spells like Steamcore Scholar and Tersa Lightbringer, shocking their owner when they're played
Its less oppressive, and while that doesnt equate to being a better Magic card from your side, I think its very cool
Outside of the more competitive spheres, I really like this card in graveyard decks like Meren or the new Beledros
