Hello, everyone! I just recently got into Legacy and would appreciate some help. THIS is my current list, except I'm playing 1 more Gitaxian Probe and 1 fewer land.
1. What do you all think about playing 19 vs. 20 lands? I like the idea of having another Probe, but I can see including the 20th land for a slightly stronger mana base.
2. Can anyone either link me to a sideboarding guide or give me some pointers? The only real guide I've found is Tom Ross's, which is great, but doesn't really tell me what to bring in or take out. I understand that you may not always want to stick to a preset sideboarding strategy and that changing things up depending on what you see from your opponent is important, but some general advice would be great.
For example, my current plan for D&T is: (OTP) -3 FOW, -2 pierce, -3 Probe, +1 Crop Rotation, +1 Karakas, +1 Nature's Claim, +2 Krosan Grip, +1 Sylvan Library, +1 Spellskite, +1 Pithing Needle
(OTD) same as OTP, but -3 daze instead of FOW
Am I bringing in too much? Karakas bouncing Thalia has helped me out quite a bit, Crop Rotation in response to Wasteland and Rishadan Port is great, the 3 artifact hate feel necessary for Jitte and Spellskite, Sylvan feels great in every fair match-up, Spellskite will at least protect an infector from STP/Jitte, and Pithing Needle helps against pesky lands, Jitte, and Spellskite.
3. Why do most of the more recent lists only have 3 Vines?
