Lightlord Draw Engine: Solr Exchange + some Qns

LODT-JP052
Solar Exchange
Magic - Normal
Discard a [Lightlord] monster from your hand to activate. Draw 2 cards from your deck, then send the top 2 cards on your deck
to Graveyard.

If Macro Cosmos cards (Cosmos, dimension fissure, Bansiher of light Etc..) is on the field, this card can still be activated right? Since the first part didn't mention that the discarded Lightlord monster must go graveyard to activate. Then I'll be able to draw 2 cards and send 2 card from top deck out of game???

Also, will scout plane effect keeps on activating at the end phase of a turn to reduce LADd's atk strength to 800?? [Similar to treeborn frog]

1) just like D draw u still can activate

2) scout plane + dd survivor only activate their effect once during endphase,ladd negate it liao they cannot come back le
