I don't understand why people so amazed by this, it is nice fit on hail team but since hail teams normally like 95% of the time have a huge weakness to fire\rock\ or fighting.It normally takes superhuman prediction or flawed opposing teams for hail teams to work.
I don't expect you to be amazed. But I do see some flaws in your argument.
1. GUTS Stone edge from
HERACROSS allows Walrein to put up a sub and then out-stall Heracross to the hail.
2. Similarly, Cross Chop from Electivire allows Walrein to use Subsitute. It is a very bulky pokemon and the hail just makes it more so. Similarly, CB Brick Break from Weavile doesn't even do 50% damage all the time, and it will die to Toxic Spikes anyway.
3. Walrein is water/ice, so it isn't weak to fire. An important asset to an hail team regardless.
As stated before, unless you're packing huge attack and stab bonuses (like Close Combat Heracross, which Walrein won't be able to get a sub up but it will survive non-boosted ones (like Scarf non-guts close combat)), Walrein will get the sub up and then out-stall your pokemon. Hell, no form of Garchomp can break the combo of Walrein. Chainchomp Draco meteor is too weak, and CB Outrage is also too weak.
Also I don't see huge difficultly in countering either are several methods in countering other than what dragontamer mention, like switching back forth between a sleep talking Cresselia and Blissey,sacrifice and kill,psudeo haze it out deal with later.
Switching back and forth gives _me_ an advantage. What? You think that I'm
ONLY going to leave Walrein in there? A free switch is a free switch and I can switch to any of my pokemon who can get a good advantage on your team. (Subseeding Abomasnow for instance takes care of the Cresselia / Blissey problem... and then most phazers (except Roar Suicune who doesn't like Leech Seed so much) can't take a NeverMeltIce Blizzard from this guy, and Blissey can't take a focus punch)
Think, it takes 2 pokemon for you to counter a single one... and it isn't even a real counter. I can just use roar and toxic spikes your sweeper. The "switching back and forth" strategy only works when you assume I'm using only Walrein. Remember, it is a team game.
Walrein is strong enough to take a pursuit from anyone (even T-Tar) and come back later, while at the same time CB Adamant Dugtrio doesn't even guarantee a 2-hit KO with Stone Edge when you factor in hail, leftovers, and a turn of protect. 53.61% - 62.98% damage according to Metalkid.
Then of course, I use either blizzard OR Surf for the guarenteed OHKO on Dugtrio.
Its more like sacrifice, revenge-counter while I switch out to my next counter to your revenge killer. You can't force a kill with pursuit or Dugtrio, and Trapinch is too slow and Walrein will out-stall. And of course, Wobuffet is banned.
,psudeo haze it out deal with later.
The only standard psudeo hazer who will roar it out first is Suicune + roar (brought up so far... please tell me if I've missed any). Walrein is faster than Donphan, Swampert, and even Skarmory. So most standard phazers simply do not work against a smart opponent.
I like the effort and thought put in threads like this,I like creative use of uu pokemon to have over used applications.Well thought out idea like this thread ,Chainchomp,growthran makes coming to smogon fun but let not go over board the idea is good but not earth shattering.
Don't get my above criticism too far :-p I do agree that this isn't an "earth shattering" idea, but it is an interesting team member and it seems to deal with a huge number of problems pretty well (particularly, the ones you brought up). And it does use a very UU pokemon for the job, which is always a crowd pleaser.
I find that the main problem with this set is the huge amount of set-up. Granted, I've gone entire battles without getting a chance to use Walrein and that is okay. Its a strategy that is there when you need it.
Also this not shot(maybe a little shot) at dragontamer but i love the way he plugs his idea in other threads it is thing of sheer beauty.
Sigh. If you don't like a defense tier analysis, don't read it. >_<. However, there is no other way for me to estimate the defensive strength of this guy. If you got a better way of coming up with the information I came up with (that is, this guy is about as strong as Weezing in Physical Def, and about as strong as Dusknoir in special defense), please tell me. Till then, I'll be using Defense tiers in my analysis.
I don't force anyone to use Defense Tiers. And I don't expect you to belittle me because I'm using what I feel is the most effective means of communication. Its barely 2 paragraphs and makes up a very small portion of my post.
I also have to give credit dragontamer again,at begin of the D/P metagame people where laughing at the use of toxic spikes like if you were using dig or blast burn.I could not understand at time why people didn't like a move that poisoned almost every poke entered in a battle.People use guts/heracross excuse but that never made that much sense to me,three main pokes with guts are afraid of gliscor but anyways I couldn't at the time make people see toxic spikes was good move but people are certain seeing it now.
That is actually a key point. Toxic Spikes is half of what makes this set good. When those rogue Drapions, Roserades and so forth come in and ruin the setup you know you're screwed, or at least put in a very big disadvantage.
