>>55592134Bellossom is like 50% bulkier and gets Strength Sap, Sludge Bomb, and Moon Blast to bolster its move pool. Lilligant has more power and speed, but Bellossom can feasibly get an extra QD up where Lilligant couldn't because of semi-reliable healing and that added bulk.
75/95/100 defenses are nothing to scoff at since that puts it closer to the Slowtwins in terms of bulk.
