Its pretty easy to make Yargle and Multani stronger in Golgari, and there are also good cards for giving them trample
In those days when the only delve threat was Tombstalker, before Deathrite Shaman, Ragavan, Nimble Pilferer, and the like highlighted peak efficiency among 1-mana threats, Mongoose was the card that let you slowly whittle down your opponents when your Delver of Secrets and Tarmogoyf were too vulnerable to removal
Three drop, ramp for free, turns into a massive creature really fast, chip damages everyone for every tiny spell cast
So make sure to pause a moment before each play and make sure you are getting the best value possible from each spell
Though many of the best already have trample, putting haste on every creature you play from that moment on can really crank up the heat on your opponents
Blue/white moxen and Mishra's being two main priorities (remember, we dont play Cities so Fellwars wont do shit)
