This card works well with "Shadow Delver" or "Spirit of the Breeze"/"Dancing Fairy". Whilst you lose 1000 LP to attack, with "Shadow Delver"'s effect, you can attack directly. You can gain 1000 LP thanks to the effect of "Spirit of the Breeze"/"Dancing Fairy", negating this card's cost.
This card has a slight advantage over "Injection Fairy Lily". Its cost is half the cost of Injection Fairy Lily's and it always has 2000 ATK, compared to Lily's temporary increase to 3400 ATK during the Damage Step only.
