Her monster has 3000 ATK and the ability to negate any Spell (so the Player can't use Mystical Space Typhoon), and her face-up Trap negates all other Traps (so the player can't use Mirror Force). In her Graveyard, she has a card that she can Banish to negate an attack. In her hand, she has a card that can negate your monster's effect during your turn, a loli that can prevent you from adding cards to your hand outside of your normal draw, and a loli that can destroy a card when it activates its effect. The Player can still make a move if they draw an E-HERO, since Super Polymerization would prevent Horus from negating it, or a Kaiju.
On a side note, those cards in her hands can get pretty expensive. Where does a loli get that much money?
