Updated by Chris Stomberg on May 11, 2023: In keeping with green's identity as the color of nature and growth, many of green's best one-drops are either a part of a killer combo or provide you with mana that later enables a combo
For this reason, youll also want to include rummaging effects, like Faithless Looting and Greasewrench Goblin, to smooth things out
Getting 2/2s simply for playing Magic is a strong ability on its own, and opens up options for mana ramp, Voltron (making 1 creature super strong through powerups), Curses like Curse of Opulence for table politicking, and several other cool, unique effects that Auras can bring to the table as you build a token army
The key parts of an overrun are mana value, trample and lethality
The bane of white-blue decks in that format was Cabal Torturer, and without Psionic Gift, the only good way to deal with this creature was to splash red or black as a third color, weakening your mana base
