If you have any [L] Energy in the Lost Zone, this attack does 90 more damage
It is believed that 30 to 40 of these cards exist, though at present, there is only one known to be graded a PSA 10
And we use Survival of the Fittest to dig up any number of creatures like Wall of Roots (infinite green mana), Wall of Blossoms (draw your deck), Spike Feeder (infinite life), Ghitu Fireslinger (infinite damage), etc
On the other side, we have Open Hostility, which backs up its lowest overall value by having the worst reprints, with only Iroas, God of Victory being all that important or of significant value
When this card leaves the field, destroy that target, and if you do, banish it
