Otherwise they are good against Burn and some fringe combo decks, but against the discard decks where i originally wanted them as additional defense i stopped boarding them in, because they are really bad topdecks. And against other more common combo decks they don't do anything. So i'm looking for alternatives that are decent against Storm and have some other applications.
Mindbreak Trap seems to have the same problem, good against Storm, but not that many other applications. I'd rather keep the Leylines.
Sphere of Resistance seems to have the most applications, against every combo deck and probably also against Delver. But i'm sceptical if it's good enough, i don't like tapping out even on Turn 2 against most combo decks. Still, it's probably a decent option.
Thoughtseize. I always dismissed that option with my very light black splash, but with some juggling around i could get to up to 10 untapped black mana sources. This is probably good against every combo deck, tapping out on Turn 1 is also fine. The only issue is the mana. I could play it with just 9 black untapped sources, but i think that's not enough. To get to 10 sources i have to cut the Veteran Explorer and replace one Forest with a 2nd Bayou (and i also have to play 3 Mox Diamonds, but i wasn't happy with just 2 anyway, to cut the third one was a mistake) - that could be fine, Explorer gets boarded out a lot, but it is a cost.
For now i'm trying out the Thoughtseize, so far the mana wasn't an issue, and i haven't really missed the Explorer either.
2. Against Delver, i'm playing with the idea try to go for mana denial a little more. Elephant Grass is ok, i tested that before, it has just the weakness that it's really bad against Chalice, and so pretty useless against Eldrazi. I'm playing white, so is Ghostly Prison a viable option? I'm trying this now, but i'm sceptical. Has anybody with a white splash ever tested that card?
Also, going with the mana denial, Choke is another option against Delver that's probably good against Miracles too.
I'm pretty sure if i wasn't playing on xmage, but on Magic Online instead, i would put at least 1 Choke in the board. On xmage the meta is different, and i don't think there are many other decks where i want Choke, but i still want to test it and see how good it really is against those decks. (Limited testing so far: Whenever i put it into play, it won me the game almost immediately.)
