MTG Salvation

As for toolboxes, I play Shred Memory. It tutors for:
Regrowth
Hymn to Tourach
Mind Shatter
Punishing Fires (If I have Grove of the Burnwillows)
Demonic Tutor
Survival of the Fittest
Bloodghast (If I have skullclamp)
among other things.

Survival also is a good toolbox. It gets Witness, R/G Titans and Shriekmaw usually.

In my Karthus deck (perfect mana) the utility lands I play are:

Ancient Tomb
Strip
Waste
Dryad Arbor
Reflecting Pool (sorta)

The deck is actual highlander though because I only play 5 basics and two are Snow-Covered.

But the fact that it's a creature means it can be abused so hard the card will rip. Like viperesque said, if he's in one deck, suddenly the game becomes about him. Have him out and you clone him? With 4 people playing you just dealt 30 damage and gained 30 life. Oh no!1! He's in the graveyard! Too bad black doesn't have a single card that gets stuff from graveyards.

I would be more than fine if my opponent packed their deck with 10+ ways to reanimate Kokusho. If a deck is going to be diluted to the point where they have to draw a tutor/entomb effect then I am fine with them going to that trouble. Kokusho doesn't get around general damage. I don't care about thirty life because any deck I made that didn't deal general damage could deal way more than thirty damage in one turn if it didn't just win the game.

Quote from Waiting in the Weeds

And green would scoop, because he has almost no answers or ways to deal with kukosho. Plummeting him would just make the opponent happy you did his dirty work. And when you're trying to aggro, fighting a lifegaining opponent is an uphill battle.

Every moderately good green deck I have seen is able to do a TON of damage in one turn. I have yet to see a green deck that would literally scoop to a 5/5 flying dragon. In 1v1 it's a measly 10 point life swing, and in multiplayer there are a ton of opponents that can also deal with Kokusho. Why would you Plummet a 5/5 that doesn't have a relevant in play ability? Sure it's an uphill battle, but between Overrun effects and just plain huge creatures, it can't be that difficult to beat Kokusho.

Kokusho seems pretty underpowered. I don't think it does anything that is actually powerful. I mean, gaining like 30 life is ok, but still not terribly impressive. Each opponent losing 5 is pretty mediocre. Decks that are competitive all do something actually powerful instead of draining a ton of life. Compared to infinite combos and time stretch and such, Kokusho seems lackluster at best.
In 1v1 he is basically a joke, and quite a bit worse than BSA (which sucks).
Compare him to ANY titan. The only one that may be worse is the black one. Maybe. I agree with RedPanda that it actually sounds fun to play Kokusho wars. And honestly, I will allow anyone who wants to play any number of cards that drain 5 from each opp at the starting cost of 4BB and 1B+ after. Not very exciting.
@Viperesque: Why would a green player scoop in response?

I play an infinite Warp World deck that does take like 30 minutes occasionally to go off. It's obvious I've won early but people just think they can get a permanent to stick so they watch me WW for like 50 ten times.

The card seems playable, but not excellent because it costs mana to activate. The fact that it is five cards is interesting because you have a higher chance of drawing a specific card than with Parallel Thoughts. If it didn't cost mana to activate I would say go for it, but since it does, I would not play it. Like best case you get Sol Ring, Mana Crypt, and then draw them all with another card, but it just seems like too much work.

Wotc does a pretty good job with funny flavor texts but what are some that you really think they missed on?

The new Mindslaver should have had:
"Quit hitting yourself. Quit hitting yourself." - Squee

I'll say it again. Needs more Thraximundar... Card's' clearly insane.

Make a non-combo Captain Sisay deck. Such a toolbox and you get to play green.

While good I never include them in my blue decks. That being said, I never try to play optimized blue lists because I don't have fun with them. I don't really think they are worth the space. If EDH were a 97 card format I would make my decks 97 cards, but if it was a format where you could play any number of cards you can bet all my decks wouldn't be the minimum and no casual deck would be playing ponder and co. And as far as this discussion goes, portent isn't playable because it isn't actually a cantrip... Slow trips shouldn't be considered 1 for 1 cards.

I have a pimp Ashling deck with 99 (FOIL) Zen John Avon mountains. I think getting that may be harder than almost any other deck.

Top is behind Strip, Waste, Sol Ring, Mana Crypt, Island and IMO skullclamp. I see people lose almost as often to their own Top and win b/c their hand is three cards bigger. T1: Top. T2/Upkeep: Activate --> Scoop b/c no land.

Vote: Sol Ring...

Quote from Meritocracy

It must be Sol Ring; a legit argument can be made for not running SDT in Sisay.

And Azami... It's pretty poor when you just draw your deck.

Needs more Thraximundar. He's no Gideon but he's a great alt wincon.

My entire playgroup decided to make decks that were all radiate effects. We made 4 almost identical copies of decks that hope to win by pissing off your opp because you have out hive mind and play Shaharazad then twin cast and such it. Except all of us had out Hive Mind, and so we took a total of 32 extra games after the dust settled. We made a blood pact that we would finish them before we ate or slept. One of my friends died halfway through the week to dehydration. We played on.

This deck didn't start as such but it has ended up a pauper version of the Canadian Thresh legacy deck. I keep changing the SB so I don't know what to post for it. The deck is a ton of fun and has a very powerful lategame. Give it a try:
