I feel like Boros Charm would be better than Lightning Bolt

Nef, Boros Charm is good, but it doesn't fill the same role as Lightning Bolt, so it really depends on whether he prefers interaction or protecting his creatures, I tend towards the former.

One suggestion I have is actually to remove Harabaz Druid. I know it kind of sounds weird, but since she's not a turn 1 drop, and you're not really ramping into anything, you'll often have way more mana then you actually need. If you'd rather keep her, I would add 1 Gavony Township, 1 Kessig Wolf Run, and 3 Mirror Entity to use that mana on something.

I like the deck, +1! A problem I see you having is the mana; maybe you could add an extra land or two? Nef I agree, Boros Charm has better synergy; I think at that point he would definitely need more land, since at 20 lands we can get stuck on 2-3 lands, conflicting with casting our creatures.

Path is what interaction we get and I find that allies usually don't need to deal with creatures that much. Boros charm would give better utility I feel

I haven't seen Lightning Bolt enough in games to be sure if it's what the deck wants, so I'm up to cutting it for the Charm. I agree with aubman02, though: if the curve goes any higher than it is now I'd need 1-2 more land drops. I could do:

• 1 Harabaz Druid --> 1 Kessig Wolf Run or Gavony Township
• (not sure which'd be better with only 2 Druids available)
• 2 Lightning Bolt --> 2 Boros Charm
