An old card, but....
first, let's see her effect...
This card's effect can be activated only during the Damage Step of either player's turn. Pay 2000 Life Points to increase the ATK of this monster by 3000 points only during the Damage Step.
Lily, besides her kawaii art, have an effect that couldn't be underestimated.
Even Honest, can't beat her. Honest user can activate "Honest" in their turn against Lily. But, if Lily's user is smart in that opponent's turn, he/she would let Lily destroyed by battle instead of paying 2000 LP against Honest.
During your turn, against opponent's Honest, you always win with Lily because her effect is in Chain Link 1 if your opponent uses Honest (Honest is Chain Link 2, and Lily resolves last, so Honest only gain 400 ATK, orz).
She also can't be trapped by Bottomless Trap Hole, and also Trap Hole.
Shrink also won't really affect her since it only makes Lily's ATK to 200, and it would be 3200 after her effect's activated.
Most of Synchro Monsters pwned by her, since a 3400 ATK is really an ouchy douchy for a level 3 monster. Not to mention, JD, DAD, etc, also can be pwned easily by her.
And now, a new Continuous Trap Card "Inverse Universe" was released in Absolute Powerforce.
Can make Lily's ATK up to 4500 by just paying 2000 LP.
Another advantage is, Lily's EARTH.
She can be revived via Kurogane. She gain extra ATK from Gaia Power.
Her original ATK is just 400, so she can be revived with Limit Reverse. Debris Dragon can Special Summon her from Graveyard, then you can instantly Synchro summon a level 7 Dragon monster.
Lily's also Spellcaster type monster. Can be splashed in a Spellcaster Beatdown Deck that rely on Solidarity.
Shooting Starbow - Ceal would reduce her original ATK to 0, but, she still a 3000 dirrect attacker.
Essentially, I said this card is awesome.
Good art, Good effect too.
