This question deals with multiple {Gruul Ragebeast} .
I have one already on the field and I cast another one on my next turn, given their effects, would I be able to have the second {Gruul Ragebeast} fight a opposing monster twice? (Once with its own effect an once again by using the effect of the one that's already on the battlefield) cause the dude I'm playing is getting pretty butt hurt about losing lol and said that multiple of the same effect are redundant and the combat by effect would only happen once since they are the same card. Any help would be great, thanks.
It's a triggered ability. When the second one enters the battlefield, its trigger and the other one's will go on the stack and resolve seperately. In short, yes, the second one fights twice. Keep in mind, This is NOT optional. Those creatures MUST fight another creature, so if you wipe your opponent's field, be careful.
RESOLVED
Oh yeah I always consider that part lol. But this guy likes to argue that's why I asked, but thank you much for your advice.
