Splashing in goblins is meta dependent everyone, I figure anybody who has been playing this deck for about 2 days will figure that out. To splash or not to splash and what to splash is sort of a big question with limitless answers, it is perhaps the leading question of legacy.
Is it good or bad? Hard to say. But it can't be definitively one or the other. It has a certain surprise factor that krosan grip can never have, and that is often very useful and gamechanging. 1cc vs 3cc is a huge difference in legacy. The lifegain can be uneventful sometimes and the split second can also be pretty mundane quite often. Is it better than krosan grip? Definitely not, but is it a reasonable alternative to krosan grip, potentially? I think so. I'm sticking to grip for now but we should always stay open-minded.
You also missed all the points GoboLord made on it only three posts up from yours.
@ Humphrey: Really? I guess that's a good point, you can't use the alternative cost on TSH if you have warchief in play! Never thought of that before. OH wait, I have, and I mention almost on every page in this thread now why that doesn't matter so I'm not going to do it for the hundredth time. The vial thing is also irrelevant and I'm not going to get into it.
