I've been thinking a lot about the Agent of Force Mars' Abilities, and I want to know...if the sac. in the sky is on the field and , your life points are even, can when the opponent attack the Agent of F. Mars with something like blue eyes. Can you activate the trap nutrient z and once your life points go up before the damage, will he get the boost too, and win the battle?!

for of all this is a rules of dueling question. but the answer is no, it wont gain or lose points during the battle.

I've already pm'd you about this, kyleoh. It seems to me like it might work (since Mars' effect would be mandatory), but you should have this thread moved to Rules of Dueling to ask the judges.

There are better ways to increase Mars's attack. Draining sheild will negate an attack and up his attack = to the atacking monster. Nutrient z is medioker but if your combo works killing a 2000+ attacker and doing damage in your opponets turn rocks. Also Butterfly dagger + gearfried + magic absorption would work well for virtualy unlimited attack. But that works for magical mirionet and no1 ever uses that. Solem wishes is also a good option.
