Id like to draw your attention to Sunforger, which has an incredible activated ability that unlocks a toolbox of instant or sorcery spells that you can search up to help deal with whatever you need dealt with at the time
Combos here, unique interactions and synergies there, and keeping your decklists on a notepad file that just shows text can be hard to wrap your head around
Cosmic Spider-Man gave my Spiders flying, first strike, trample, lifelink, and haste, so I was able to swing unblocked to kill the Helga player and knock the fourth player all the way down to a much more reasonable life total
Mono-Green is often trying to curve out against opponents, so you need cards like Trail of Crumbs: good mana sinks that allow you to stay high on resources throughout the game
It says a lot about Magic that simply focusing on one type of spell can create such a tangible aesthetic and strategy for a deck
Im definitely concerned with this decks early game
