What are the Biggest Limited Bombs of Old MTG?

At the start of each of my set reviews, I provide a grading scale, and it looks like this:

Retired and inducted into the Limited Hall of Fame: Pack Rat, Umezawa’s Jitte, The Scarab God.

• 5.0: The best of the best. (Fable of the Mirror-Breaker. Jugan Defends the Temple. The Wandering Emperor.)
• 4.5: Incredible bomb, but not unbeatable. (Junji, the Midnight Sky. Ao, the Dawn Sky. Blade of the Oni.)
• 4.0: Good rare or top-tier uncommon. (Behold the Unspeakable. Life of Toshiro Umezawa. Imperial Oath.)
• 3.5: Top-tier common or solid uncommon. (Kami’s Flare. Network Disruptor. The Modern Age.)
• 3.0: Good playable that basically always makes the cut. (Fang of Shigeki. Sunblade Samurai. Moonfolk Puzzlemaker.)
• 2.5: Solid playable that rarely gets cut. (Tamiyo’s Compleation. Simian Sling.)
• 2.0: Good filler, but sometimes gets cut. (Historian’s Wisdom.)
• 1.5: Filler. Gets cut about half the time. (Clawing Torment. Bearer of Memory. Upriser Renegade.)
• 1.0: Bad filler. Gets cut most of the time. (Moonsnare Prototype. Reckoner Shakedown. Futurist Sentinel.)
• 0.5: Very low-end playables and sideboard material. (Bronze Cudgels. Storyweave. Ambitious Assault.)
• 0.0: Completely unplayable. (Mirror Box. One with Nothing.)

The note at the start mentions the Limited Hall of Fame, and today I’ll be expanding on that, and presenting the best cards of all time when it comes to Limited play. I’m going to break it down by era, since like in sports, comparing old players to new ones doesn’t make sense (nor does it stop anyone from doing it). I’m also going to relax the rules of entry a bit – this isn’t the top couple cards of each format, it’s all the A to A+ cards, as that’s a lot more interesting to take a look at.
