A LV2 ST07-002 EVA-02 -Engagement Complete- is on my field when another NERV spirit is blocked and destroyed in battle. At this time, can I use the effect on this spirit to draw a card?

When I use the LV3 effect on a copy of this spirit with six cores by placing five of them into my trash to reduce my opponent's spirit to zero cores, is a core from my opponent's life placed into their reserve even though this spirit is now LV1?

Since this spirit must attack if able, does that mean it has to attack first during my attack step?

If this spirit has not attacked yet and my opponent's magic effect that ends my attack step activates while another spirit is attacking, does the step end even though this spirit hasn't attacked?

This spirit and an ST07-004 EVA-01 -Operation Yashima- are on my field refreshed when my opponent uses a BSS02-133 Thorn Prison. At this time, if I exhaust this spirit and my ST07-004 EVA-01 -Operation Yashima- can then be selected by my opponent's effects, does that mean I have to exhaust it too?

When summoning an ST07-004 EVA-01 -Operation Yashima-, can I reduce its cost by yellow, red, and purple simultaneously using the one symbol on this spirit?

My opponent blocks my attacking EVA-02 spirit, and both spirits are destroyed since their BP are equal. At this time, can I draw a card using the LV2 effect on this nexus?

If I have two of this card on my field and five cards in my hand when one of my EVA-01 spirits is destroyed, does the effect on each of these nexuses activate enabling me to draw two cards?

Does 【Armor: Purple】 protect against the LV2 effect on this nexus?

I use this magic card while I have a Shinji nexus on my field, removing a core from one of my opponent's spirits with three cores and placing it into their reserve. When I destroy a spirit with two or fewer cores after that, can I select the spirit I just removed a core from and destroy it?
