What is the best magic card ever printed that is not power nine?

Oooh I like the other answer that goes by colors. Ok, so here’s my picks for each color

Green

One of the single most broken creatures ever printed. It just is, abused with so many cards that can bring her back, and every time she can re-use any card you already used? awesome

Red

One red mana, put any creature from your hand into the battlefield. Red is actually probably the weakest color overall in Magic, but this effect is crazy powerful and I do think it is one of the more powerful cards in Magic

White

With one card, its a wrath of god effect + armaggeddon effect + discard effect. I mean, wow all with 2 mana

Blue

Blue has some of the most broken cards in the game, so it’s gonna be hard to pick just one. I’ll go with Mana Drain though.

Designers must have been high when they made this card. Now its even better due to no mana burn

Black

Also too many crazy powerful black cards. I’ll go with this one though

Re-use my black lotus and ancestral recalls? Why yes I will…

Land

Arguably the most broken land in the game. It’s either this or Bazaar of Baghdad or Library of Alexandria but I’ll go with the Academy

Artifact

Also, too many broken ones to name. I’ll go with this one though. I mean, cmon it may as well be part of the Power Nine, its arguably better than a Mox
