I wouldn't run Library. Also, the deck should probably run Infernal Contract over Meditate, as that was the original build.

Maybe run a couple Karplusan Forests, Wastes, and Brushlands and throw in Balance and Wheel. Balance is a tough call. It's a 2 mana Wrath of God and it's almost always LD in the deck, but it's almost always going to end up being hand destruction on me. Recall is pretty good too. And in this deck, Chaos Orb is the single best removal spell ever printed.

Yeah, I guess Balance is useless. I'll probably end using Wheel because it's one of the cheaper cards available and it's card draw. And card draw is never bad in a combo deck.

Well, I imagine the reasoning is because it's not in Prosperous Bloom and that's the only deck anyone tries to build because it's the most competitive deck that can be built.

I think this is the final list I'm going to use:

4 Squandered Resources
4 Cadaverous Blooms
4 Chaos Orb
4 Infernal Contract
4 Natural Balance
4 Prosperity
2 Drain Life
2 Hurricane
1 Black Lotus
1 Wheel of Fortune
1 Recall
1 Vampiric Tutor
1 Zuran Orb
1 Ivory Tower
1 Aswan Jaguar

4 City of Brass
4 Forest
4 Karplusan Forests
7 Swamp
6 Island

The original deck only used a single Drain Life, and Mike Long famously bluffed his way to victory in a match despite having lost his final one. Two should be fine. It's a combo deck, and it only needs one to win in a duel. In multiplayer, all I need to win are a single Drain Life and a Hurricane. Instead of a third copy of either, I'm going to run Aswan Jaguar. It's a lot cheaper, and while unplayable, it's hilarious.

Prosperous Bloom is a famous combo deck from Mirage Block. This is the original deck list:

4 Cadaverous Bloom
4 Natural Balance
4 Squandered Resources
4 Prosperity
4 Infernal Contract
4 Impulse
4 Vampiric Tutor
2 Memory Lapse
1 Power Sink
1 Elven Cache
1 Emerald Charm
1 Drain Life
1 Three Wishes

4 Undiscovered Paradise
3 Bad River
7 Forest
6 Swamp
5 Island

You need three cards to win: Cadaverous Bloom, Squandered Resources, and Prosperity. You can potentially win on Turn 4, once you drop Prosperity.

Here's the God Hand:

Turn 1: Swamp. Cards in hand: 6
Turn 2: Forest, Squandered Resources. Cards in hand: 5
Turn 3: Any land. Cards in hand: 5
Turn 4: Any land, Cadaverous Bloom.

You have now have four cards in hand. You sacrifice your four lands to Squandered Resources for four blue mana. You discard three cards to Cadaverous Bloom for 6 additional mana. You play the last card in your hand, Prosperity, for 9. You draw 9 cards. You pitch two, probably lands, and play Natural Balance. You sac the five lands you get with Natural Balance for another 4 blue mana. You Prosperity for 14. Discard card 13 cards from your hand for 26 black mana, Drain Life your opponent for 24. Game Over.

Obviously, it doesn't always go that way. Sometimes you might need to Prosperity three times for the win. The original deck uses Contract, Impulse, Three Wishes, and Vampiric Tutor to help get the combo off as early as possible. Vampiric Tutor was not restricted in Mirage Block. IIRC, there was no restricted list for block formats, only banned lists.

Ah, my bad. I apologize. Should have read, uh, ALL THE WORDS on Resources. I started reading it, then thought I remembered.

Though you can potentially win on Turn 3, Turn 4 is the better play. Prosperity for 6 is too risky for my tastes. The longer you can wait to set off that first Prosperity, the better. Unless you're playing against control.

Given how the deck works, I should probably run a single mountain and 3 K-Forests. That way, Wheel can used as a combo-saver after the first Natural Balance has gone off.

Aswan Jaguar is the only Astral card to ever receive a physical printing.
