Finneas, Ace Archer gives each other creature you control that is either a Rabbit or a token, something that Rabbits are great at making in Bloomburrow, a +1/+1 counter whenever they attack
Whether its through tokens or giving other creatures the vampire creature type, this tribe always looks to expand its ranks
Copying a Map token or something is certainly less exciting, but sometimes that will be useful A 4-mana with Ward 2 isnt a complete disaster, and this has an effect that synergizes well with Explore and Green/White in general has several cards that pay you off for having cards that have power higher than their base power, so it doesnt seem like a build around grade is necessary here
Some commons are worth money, especially specific foils or older cards that get played in formats like Pauper

Poison the Waters ought to be an excellent sideboard card, and its probably good enough to make the main deck in more controlling black decks
