Forum:Muli-trigger effect?

I got a question on about how much CAN stardust dragon/ assault mode negate? for example...what i heard is that stardust dragon/AM can negate pretty much any effect that has "can" in its effect. so im wondering if it can negate the effects of kalut, honest, and gorz...since their effects are an option for them to use. And can someone please tell me the definition of what a multi-trigger effect can do? I read in the wikia card rulings that it can pretty much negate anything on activation besides from spirit reaper, marshmallon etc... i also read that the multi-trigger can be used in battle, damage calc. So... any feedbacks?
