My poison deck

[Maraxus of Keld]

Creatures:

4 Marsh Viper
2 Sabertooth Cobra
2 Peacekeeper
1 Fountain Watch

Others:

4 Fire Whip
3 Fertile Ground
1 Fruition
4 Taste of Paradise
1 Wrath of God
2 Spiritual Asylum
1 Feldon's Cane
1 Mangara's Tome
1 Bubble Matrix

Lands:

10 Forest
5 Mountain
7 Plains
1 Shivan Oasis
2 Thawing Glaciers

The strategy in this deck is simple: protect myself from attacks with Peacekeeper until I get a Marsh Viper (or Sabertooth Cobra, in a pinch) enchanted with a Fire Whip, then I throw up the rest of my protective wall (Spiritual Asylum, Fountain Watch, Bubble Matrix) so that the only way to hurt me is direct damage and the only way to hurt my creatures is mass effects like Wrath of God or the Disk. I would use Ivory Mask too, but I don't own it. Anyway, at this point, I have an enchanted Viper that can tap to load up the opponent with poison counters, and nothing of mine can be targeted, nor can anyone attack. The rest of the deck is just speed (Thawing Glaciers, Mangara's Tome, etc.).

And yes, this deck is less than 60 cards, but it was made under 5th edition rules, so screw the rule, it was legal then.

Oh I remember this deck.

i am amazed that it is that good of a poison deck without using black

[Maraxus of Keld]

Black poison creatures are inferior. Swamp Mosquito is nice because it flies, but 1 Crypt Cobra and 1 Pit Scorpion are crap. The Cobra is the biggest poison dealer in the game, but it's still only 3/3. Plus, the Mosquito and Cobra have to attack and not be blocked, rather than just dealing damage.
A straight poison deck can't go up against most decks in creature combat, as the creatures are weak and not very numerous. Therefore, the only way I have found to make a successful poison deck is to build a defensive wall and provide non-combat ways to deal the poison, such as Fire Whip.

i hate poison
it's sooooo cheap
no way to get rid of it

[Maraxus of Keld]

It's called Leeches.

And poison is hardly as cheap as Mortal Combat, Test of Endurance, Coalition Victory, Epic Struggle, and the like.

[Volrath, the Fallen]

my zombie deck takes care of coalition victory. hehehe

"whats that? you have one of each land? nope, all your mountains are swamps........oh, one more thing, i have a zombie master. SPLAT!!!!"

[Disco Bandit]

yeah well...
i have only been playing for a couple years...
plus i've barely seen any of the older cards anyway...

[Maraxus of Keld]

I made some changes to this deck, including cutting red entirely. I replaced the Fire Whips with Viridian Longbows, and I added a few other cards. I'll put up the changes in a day or so, whenever I get around to it.

[Maraxus of Keld]

Oops, realized I never put up the revised decklist. Here it is:

9x Forest
7x Plains

4x Marsh Viper
2x Sabertooth Cobra
4x Seeker of Skybreak
2x Peacekeeper
1x Fountain Watch

4x Viridian Longbow
1x Lightning Greaves
1x Darksteel Pendant
2x Bubble Matrix
1x Mangara's Tome
1x Howling Mine
1x Feldon's Cane

3x Fertile Ground
2x Spiritual Asylum
1x Remembrance
2x Sylvan Library

2x Disenchant
2x Naturalize
3x Creeping Mold
2x Elven Cache
1x Fruition
2x Taste of Paradise

But now the deck's about to undergo another revision.... I'll probably post that one too.

As if this deck wasn't a big enough a pain, it just got worse, hehe.
