No other green 3 power guys for 2cmc or less after rotation.
Kraul Harpooner is 3 power for 2 mana.
Glowspore Shaman if you're running GB like everyone will be because of Assassin's Trophy.
Or GW Elves because of Conclave Cavalier, Emmara, Soul of the Accord and Assure // Assemble. You don't need a 3/x on turn 2, you only need a 2/x (Emmara and Thorn Lieutenant), then a 5/4, then a 4/4. Pretty simple curve !
