The issue I've run into with Ensnaring Bridge that I've run into is sometimes I already have Blood Moon out and I draw enlightened tutor which I can't cast unless I find lotus petal and then die to some 1/1s. Punishing Fire, while obviously not as good with Blood Moon still out would be able to answer that. Perhaps this is just an argument to include a basic plains though and to make sure I have 4 arid mesa. Also I have run into issues where Noble Hierarch or a SFM with Jitte has been able to get around blood moon. Also, it feels like you're saying we don't need removal and if that was the case why would we run firebolt? Sorry if I am misunderstanding you. I do agree that Blood Moon is generally more important than Grove but I'm not convinced turning off Grove is the biggest of deals because Punishing Fire still functions (though as a worse bolt).

I'm not saying that this would be better than the r/w version. I just feel as though I've been seeing a lot of fair decks lately and that this engine is very strong against them. There's a very real chance that tutoring for E Bridge is just better and that I've been just getting screwed by what decks I've had the opportunity to test against. For the record, I'm trying to take the experience of those who have been playing the deck longer that's why I was asking for people's opinions rather than just jamming it in but the initial responses weren't very helpful. Also, since it wasn't actually my idea I'm honestly not 100% in love/convinced with the idea but I still thought it could just be worth discussing. There's always a chance any deck that has been established for some time will adapt to changes in the meta-game and at the very least discussions should serve as a learning experience.
