Flower-gift boosts the teams Attack and S.Defense by 50%, that includes Cherrim, so it can be used in a single battle! With Jolly its Attack goes up to 324 which is pretty good! Sunny-day is in-case you do not have Sun-support, otherwise go with Swords-dance. Seed-bomb is STAB, but if you want to have a move to beat Subs, Sashes, and Sturdy then use Bullet-seed. Return is good neutral coverage. Nature-power becomes Earthquake in PO/Wi-fi battles so it is great coverage.
