Skyscythe Engulfer

Reach on a green fatty is old news; the second line is the interesting move. Green has always had reach as its answer to flyers, a way to shoot them down as they come in, but it has rarely been given a way to attack past them. A 6/5 with reach and trample already blocks anything in the air and pushes damage through chump blockers on the ground. Adding "can't be blocked by creatures with flying" flips the usual assignment: instead of green sitting back and swatting attackers out of the sky, this thing runs at the red zone and dares an opponent to find a ground blocker fast enough to matter. Fliers, the traditional stall against a big green ground creature, are demoted to spectators. Trample then does the rest, turning any smaller blocker into partial mitigation rather than a real stop. It is a deliberately one-directional beater: reach keeps it honest on defense, but every keyword on the card is pointed at making a large body impossible to gum up. The rate is unremarkable for six mana, which is exactly why the third ability exists, to buy back the tempo a slow green threat usually surrenders to evasive decks.
