i really cant beat wallrein everything i tried failed maybe if i use breloom it will finally stop tormenting me...T_T
If it helps, pure water types and Empoleon are the only types who resist Blizzard + Surf, a combo I use over and over in my entire team. Water + Ice is actually a very decent attack combination, especially coupled with the fact that Blizzard has a huge attack power with no drawbacks in hail.
Again, Rest/Roar Suicune works wonders when Walrein comes out. Rest off the toxic Spikes, Roar Walrein away. Or, come in asleep so the toxic spikes don't hit you and then roar walrein away with either sleeptalk or just plain old roar (only 2 turns of sleep anyway). Suicune is one of the pokemon that gives me the most trouble.
Toxic Spikes of your own hurt my team very much as well, especially as toxic spikes are eaten up by many common toxic-spikers... or at least they are immune. (Tentacruel, Roserade, Drapion absorb them, and Forretress can spin them away)
Simply put, any kind of status hurts Walrein. But continuous damage like burn, poison or toxic hurts the strategy the most.
Rain Dance helps a lot.
Oh, and contrary to earlier hypothesis... T-Tar is not that big a deal when the toxic spikes and substitute are out. Protect on the first turn... 6 %damage. Substitute on the next turn... and if he's slower the sub will fail, then protect. If he's faster, the substitute will replace the one he just destroyed with Crunch / Stone Edge / whatever. 12% damage. Protect, 18% damage... running total of 36% damage so far. Continue sub/protect as you see fit, and then surf for the win. Its ~30% damage after the sandstorm boost, so if you surf on the 4th turn, that is 24% (toxic) + 30% damage or 54% damage on the last turn. Protect on the 5th (30% damage from toxic) and you've defeated T-Tar or at least forced a switch out.
So CB T-Tar is no worries unless it comes in when the sub is down.
About taunt... protect will block the first taunt, and he will not break the substitute if he taunts on the 2nd turn (obviously). Then on the 3rd turn, you use surf. So either way, you are dealing at least 50%+ damage to T-Tar with minimal risks from him. The worst that can happen is dragon dance -> taunt of course, which really does pose a risk to your team. Just switch out to frosslass, hope for a miss... then Destiny bond. Lol.
Similarly, Taunt + Dragon Dance Gyarados poses a serious threat to a walrein team if Walrein is injured and isn't carrying Blizzard. Dragon dance on the first turn, taunt on the second. Keep dragon dancing, as after the 2nd dragon dance nothing can really stop you except focus sash pokemon (and in this case... focus sash ice pokemon due to the hail). Blizzard on Walrein stops this strategy cold, because I'd use Blizzard on the first turn for some 35%ish damage on BulkyDos as you Dragon Dance / Taunt, Blizzard again as you break the sub or taunt, and then Blizzard a 3rd time for the kill.
Which is a
major advantage to blizzard over Surf mind you. To kill one of the hardest counters to this strategy just like that... Surf has the obvious advantage of doing stuff to more common walls like Magnezone. But I guess you can run Gliscor or something like that.
EDIT: I should note that Breloom, who practically dies to STAB Blizzard from any of my 4 pokemon touting the move... or weavile ice punch... is not exactly a threat. Lol :-p
Wait, 5 Pokemon with Blizzard or Ice Punch? Who doesn't have an ice attack? Walrein :-p Even to those who resist, Blizzard is a great attack, and spamming it is the best way for you to get the 10% freeze rate to happen. Not to mention, Switching in a wall who can take Blizzard gives me an openning to switch Walrein or Abomasnow in (Don't underestimate the power of sub-seeding any wall), with perhaps exceptions to Magnezone.
