Q.1

Player A: dd assailant attacks a hydrogeddon which is equiped with blast with chain.

i know that they are both removed but my question is would i still get hydrogeddons effect of summoning another to the field

Q.2

would treeborn frog be special summoned if there is only a field card on the field.

thats all.

thanks in advance.

1. No because Hydrogeddon has to remain face-up on the field in order to be able to Special Summon another.

This is why if you suicide a Hydrogeddon into a 1600 monster, you do not get to Special Summon

2. No...because you have NO Magic or Trap Cards on your field....none...Field Magic = Magic Card on your field.

ok thanks. thats all i needed to know.
