You should only allow Baseball if you have a certain number of cards in library. Even if you have 3 cards left, you have just stacked your next 2 draws in the order you want. With 6 cards, if you baseball 2 times in a row you stack the rest of your library. Getting to both dig 3 and choose the order of the cards is too powerful for a small library.
Suggestion: You may only Baseball if your library is at least half its starting size (20 in Limited, 30 in Constructed).
That not only avoids the situations where Baseball stops you from drawing to death, but also prevents abuse from library stacking. Besides, you don't really need Baseball beyond the first few turns. You just need it in the first few turns to hit your first land drops consistently.
I assume Burn was brought up because Burn is just more abusive about it. The biggest drawback of Burn is that you can manaflood or lose to manascrew. When you remove that variance, it becomes a combo deck that basically always wins the game on turn 3-4. That invalidates slower decks.
Maybe there should be a gentleman's agreement not to play Burn in this metagame. The point of the house rule is to make random kitchen table creature decks more consistent, not increase Burn's goldfish rate.
There's a far bigger problem than just considering what lands to make eligible. You just made Brainstorm, already the best card in Legacy, even more broken. Interactions with Sylvan Library and Ponder are also goofy. Thank goodness Sensei's Divining Top is banned.
Ineligible lands should start with: Strip Mine, Mishra's Workshop, Tolarian Academy, Bazaar of Baghdad, Library of Alexandria, Gaea's Cradle, Karakas, Dark Depths, Maze of Ith, The Tabernacle at Pendrell Vale, Serra's Sanctum, Wasteland. Most others should be OK. Actually even Wasteland might be fair, since the opponent can find new land as easily as you can find new Wastelands, and Wasteland even gets slightly worse when its much harder to get manascrewed.
I don't think it's worth using Baseball to "topdeck" lands in the late game when your library is thin is worth eventually being able to work off a stacked deck, but I could be wrong. Another alternative is to allow each player just 3 "at-bats" with Baseball per game.
I agree fully with your assessment of Burn archetype abusing this a little more than other archetypes. Other decks benefit as well, but straight Burn-your-face-with-LavaSpike, Rift Bolt, Lightning Bolt, etc. might get a little too much of a boost.
Banning Brainstorm would probably destroy cause rioting. Ick. But I like your suggested list, but think Wasteland would be fine to get with Baseball. But again, Legacy wasn't what I really was considering much when writing this rule.
