After summoning a Needle Token to your opponent's side of the field with this card, you can destroy that token with "Fragrance Storm" to draw a free card (or two if the first card drawn is a Plant-Type monster).
Make sure to summon this beforehand, but you can then combo "Black Garden" to summon a Rose Token with every monster this card battles and destroys.
Using "Shrink" will reduce your opponent's ATK making this effect more reliable.
This card can be used in an OTK with "All-Out Attacks" to keep forcing the Needle Token into attacking "Cactus Fighter" every time one is Summoned. If you only control this face-up monster, that will keep happening until your opponent runs out of Life Points (provided that "Cactus Fighter" destroys one of your opponent's monsters during your opponent's turn).
A small combo that can be used is with "Timeater" to have a "Needle Token" to destroy safely for it, if in fear of a card like "Sakuretsu Armor" or "Yomi Ship" may be used to protect or counter the attack.
