Battle step questions & horn

Battle Phase

Turn player declares attack on opponent monster
Turn player uses priority to chain book of moon on opponent monster

Can opponent chain Dimension Prison to the attack?



Horn of phantom beast
If monster equipped with horn attacks snowman eater, does controller still draw?

Yes, if the book of moon is activated during battle declaration.
However, if book of moon is activated during battle step (after battle declaration), opponent cannot chain dimension prison to it.

You mean the snowman eater destorying the attacking monster equipped with the horn after battle? If so, no (rmb blackwing shura, their texting of the effect are the same)
