Keep dreaming. This card is a good in theory-awful in reality. You do realize:
1. You need a f/u plant monster to acivate it.
2. Your opponent to attack the plant monster.
3. It is not chainable.
4. Cant destroy deffence possition monsters (useless vs super heavy samurai).
5. Is a trap.
Even aromage decks never use it.
If you want a predaplant tech card try rose archer in this trap heavy meta.
Sadly, you are right. I tried this a long time ago with aromage. But what sucks the most about it is that it ONLY works if you have a plant. Whereas the real mirror force could always work. So if your field is empty, this is a dead draw with no way to protect yourself. Sure, it sounds amazing, but it's better in fun decks.
the superheavy example is not relevant as most likely nobody plays it and u would lose to them anyway with aroma.
5.And what if its trap?
the chainable thing is right.too many br removal options are there.not only spells but monster effects too
Well to answer about 5: Traps are slow and extremely vulnerable. If you choose to run them they either have to be tremendously important for the deck to function (e.g. navigation, blessed winds, onslaught etc) or atleast have a good effect AND to be chainable. It is no surprise many meta deck nowadays dont even bother to run trap cards (bw, heroes,dragounity).
My point is those deck are not running traps not because of the reasons you talked about which is that traps are slow and vulnerable. The reason they dont run traps is because their play style done really need traps.
