I am a beginner and just want to ask about this card effect. 1.  If in this round, during the main phase, I down 2 earth beast and lastly a plant signi, this spell card still got effect? 2.  Should I activate this spell card first "before or after" I down my signi? If I use this spell after I downed my signi, then still got effect?
