Aromage monsters have multiple effects whenever you have more LP than your opponent, or when you gain LP. Pair this with cards like Rose Lover to help special summon plant monster(s), and making it immune to traps for a turn can win games pretty quickly.
Rose Lover is quite crucial in the deck. It can be used to special summon any plant type monster in your hand, regardless of level, and also making it immune to traps for the turn. This helps with summoning a high level plant monster, or simply making sure you won't get affected by cards like Mirror Wall, or Wall of Disruption. Using it to special summon monsters like Aromage Bergamot if you already have higher LP than your opponent can catch your opponent by surprise and potentially deal high piercing damage to end the duel.
The field spell Aroma Garden helps with gaining LP, activate Aromage monsters' effects, and increase their attack. It's often good to activate it when you get the chance, but if you have Aromage Rosemary face-up and there are no other face-up monsters, you will end up having to switch its position to defense. If your LP is at equal or already higher than your opponent, you can start by summoning Aromage Jasmine, then summon Rosemary before activating Aroma Garden to switch Jasmine to defense.
Since Rose Lover can special summon a monster and it's activateable from the grave, you can go for an offensive tribute take by summoning Rose Lover and Enemy Controller to take control your opponent's monster. Then special summon a plant monster from your hand, and it will be immune to traps this turn. If the monster you special summon has high attack, it can catch your opponent off guard and win you the duel.
I can only hope they are planning to release Dried Winds, Humid Winds, and Aromage Cananga at the start of 5Ds era, releasing them at the same time as Aromaseraphy Angelica (Tuner) and Aromaseraphy Rosemary (Synchro).
Even better, release Links into Duel Links already so we can get Aromaseraphy Jasmine as well xD
Another possible build makes use of Jasmine combined with Aroma Garden, Air Hummingbird, and other LP healing cards, plus Spirit Barrier + Astral Barrier combo.
You basically stall until your LP is high enough for Ra to deal 9999+ damage.
Astral Barrier + Spirit Barrier combo protects your monster and LP from battles.
I almost fainted when I saw Jasmine at the card trader a couple days ago after not seeing her for weeks. I'm assuming that the true potential of the deck needs 3 of her. But I am so tempted just to try it now for fun anyway cause I have everything else.
She is still in the "new" inventory. I saw her last night. I told Konami in a survey a long time ago that I was afraid that I wouldn't have time to get them all from the card trader before they disappeared and asked to make them stay forever. Not long after that, we received the regular inventory for the older cards.
