Harmless Offering and Darksteel Relic, undoubtedly two of the best cards in MTG in my opinion

Hyalopterous Lemure for the mistake art

also Elvish Piper

Actually I just discovered Root Greevil. Could you add it?

darksteel citadel, ghostly prison, pithing needle, dark depths, mox jet, dark ritual, myr retriever

Jin-Gitaxias, Core Augur !

I'll go with Chainer, Dementia Master. +1

How about Uncle Istvan? +1

I'll choose Indomitable Creativity.

Ghave, Guru of Spores! I can’t believe he’s not in here yet.

If I could pick a second, it would be Doubling Season. I also can’t believe this one is missing, too.

I think this needs Crow Storm.

Stormtide Leviathan and 13x Terrain Elemental because that's how many copies of it are in my collection

Please add Sigiled Starfish, it's great!

Goblin War Strike
