Land: In Legacy 22, In Pauper 22

4 Inkmoth Nexus

4 Breeding Pool

2 Verdant Catacombs

2 Watery Grave

1 Guilt-leaf Palace

1 Darkslick Shores

4 Forests

2 Islands

2 Swamps

Green Cards: 22 In Legacy

4 Mutagenic Growth (2 In Pauper)
3 Giant Growth

Blue Cards: 10 In Legacy

3 Distortion Strike

4 Blighted Agent

3 Spell Pierce

Black Cards: 6 In Legacy

4 Plague Stinger
2 Virulent Swipe
Having 4 Melira, Sylvok Outcast is a good idea for a sideboard, especially since via the law of Legendary Creatures, one destroys another, such that if your opponent is playing poison, then you will have some really good defense.
