Read the Bones is solid and is definitely one of the better black draw spells. However, Black has access to the best tutors in the game and can get is draws / extra tutors from other colors, so RTB isn’t very necessary unless your cube is lower powered and / or huge.
I think there are a lot of powerful lands in this format that need answering, and Riders is still one of the better ways to do that. More importantly, it's an abusable 2-power ETB trigger creature for the 'Lark/Recruiter/Feldon/Vat shenanigans, and it's a powerful target for those kinds of effects.
LD as a strategy was a little linear and parasitic in this format. But it's certainly powerful. Both in cube and in the Old School format(s) if that kind of deck is what you're looking to do.
I think that for smaller cubes, there are enough great red four drop creatures now that Avalanche Riders doesn't quite make the cut anymore, although its one of the more brutal cheap creatures to blink or recur a couple of times, since it can put you so far ahead of your opponent.
I have no problem with mass land destruction as a way to close out a game, such as Wildfire, Upheaval, or Armageddon. I don't run dedicated LD cards like Stone Rain because they seem too narrow on their own, like cards that do nothing but mill your opponent. We've found that even aggro decks would rather have another threat or burn spell, or just pay one more mana for Armageddon.
I always liked the look of him but haven't included him.
I like land destruction but it needs to be precise or bring the game to a close pretty soon or it can be more of a pain. I recently got wastelanded 3 time on a turn (Wasteland, play Sun Titan returning Wasteland, reveal immediate action to attack with Sun Titan and get back Wasteland) in a 3-man game, it was pretty miserable and didn't bring the game to a close. I worry Avalanche Riders would be a bit too easy to recur in the same way.
I used to run Stone Rain or similar cards in an early iteration of my cube. I have considered adding Pillage again, it is probably my favorite of the LD spells.
I enjoyed it a lot in one of the Duels of the Planeswalkers games, it was solid and usually got about 3 or 4 birds. I guess in a format with fetches she gets better but its not something I currently run.
Bird stories? So I was a bar once and this bird come up to me, had the biggest pair of... Wait I think I misunderstood the question. I like birds; I don't have any great stories about them but I often stair and pidgins etc. if I'm waiting on the train, they are kind weird to observe.
A friend has run it for a while, along with a lot of MODO cubes, and it's alright. Sometimes it makes a ton of fliers, other times you stop drawing lands or it dies since you can't just do nothing on t4. It's definitely worse than the top tier options, but totally acceptable and can be real great too.
Emeria Angel seems cool as a way to keep your land draws relevant, even later in the game when you start running out of spells. The birds having evasion is great for picking up equipment and keeping the pressure on while flooding out, also. Outclassed due to how good white's other options are, not because she's not good enough on her own necessarily.
Don't really have any bird stories of my own, although there was this one time when I was stuck in traffic that a bird flew into my windshield, crash landing in the lane next to me. After a second, it just stood up and walked to the side of the road, strutting its stuff like nothing had happened.
He never really interested me, seems ok filler in a spells matters deck but pretty poor everywhere else.
Storms are fun. We recently had some storm that was meant to be a big deal, but it was pretty disappointing in the end (in the city anyway) although some of the worry was probably in the "just in case" vein as the news was full of america being battered by storms. I think storms carry a bit less danger here than in America since we tend to build houses from bricks metal rather than wooden frames (or so I have been lead to believe).
While I do think that Izzet wants a strong reward for the spells matter deck, I don't think this guy quite gets there. I would love to see a payoff on the level of Monastery Mentor in Izzet eventually.
I don't particularly mind storms, living where I do we get enough rain that I'm used to them by now. I'm not a fan of snow, though.
