Great Forest Druid

Green rarely gets a five-color mana source, and when it does, the body usually shrinks to nothing. This one keeps its four toughness, which changes what the card is for entirely. A 0/4 that produces any color is not a mana dork that trades away the moment it becomes inconvenient: it survives most early aggression, blocks a two-drop indefinitely, and still fixes for a splash while it does. The Treefolk wall body is the whole trick. Where a Birds of Paradise or an Elvish Mystic accelerates you and then dies to the first ping, this one is a mana source that also holds the ground it stands on, which lets it double as a fixer in decks that expect to spend the early turns absorbing damage rather than racing. The zero power is the price: it never contributes to a clock, and a card that taps for mana and blocks but deals no combat damage is a defensive investment, not a tempo one. That trade suits it to grinding, color-hungry midrange far better than any curve-out plan, and it means the card asks a specific question of a deck: are you willing to spend a two-drop slot on a permanent that stabilizes and enables rather than one that pressures? For decks that are, the four toughness is doing work no one-drop mana creature can match.
