Anyone have suggestions on what monsters to use to help beat these warmasters?
Like elvira, remntar, sherezar?
Thx

Elvira and remtars positive effects can be removed by demise,warspellz,sammy
0 cooldown extra turners (zyla,voltaik)can be good against sherezaras he opens with CD activated i believes.
If you have elvira+an anticipation you can make sherezar use his extra turn clear positive then use shining fever(faraday) to apply DOT (if he has uriels essence) and on his second turn he should die from DOT meaning he wont get his second go to CD activate you and allow you to kill him before it is his turn again.
Anything with high damage elemental/extra turns can take care of remtars trait.

Rocigon PWNS Elvira.

Elvira only works if she is the slowest monster on the team. Just put gold runes on her to make sure she goes last - then the evasion will work for all allies.

@clackers that’s not how it works. You trying to lose?

@clackers you do realise elivras evasion is applied at the start of battle? Not when she gets a turn

Most likely using one of your own, the ones you described are the ones that I see are most used on Legendary leagues on defense, Necro and Thalassa are there too, depending on the league you may be facing them not completely ranked and there's where other non-warmaster monsters can be used to defeat them, good combination is using monsters that can clean possitive effects, here's a list that most likely needs to be updated Evasion and Counters and use monsters that can trait disable, like Ingenica and a damage dealer, and again depending on the league you are it is very likely that you need to use warmasters to beat them.

I'm using a Talos to trait disable and hack warmasters when speed allows it, samael is great for cleaning possive. etc. etc.

I'm sure there are many strategies that people use, but those I think are the most general advise I can give you, each pvp battle is different and with all the variety we have now is not really possible to have a team that is able to either defend all attacks or defeat all defenses.

@vargranger But the evasion only lasts until your monsters has had its turn?

So if I used my denier (hackster) to go first, then he wouldn't have evasion anymore.

What you really want is the opponents to be faster than your monsters, then nothing would hit.

@clackers the problem is your hackster has the wrong runes on. Simply make your hackster slower by not running all speed.
As for elvira why not run team strength/life something beneficial to your team rather than gold runes.

@clackers evasion will just make sure you get a chance to go. Keep the speed on hackster. With evasion on even if your hackster isn’t fastest it will still go. Don’t attack another evasion team that’s all

Sherezar can be contained with the following team:

Copperbeard or Bo Tai, full speed
Two artifacts who are slower than Copperbeard or Bo Tai, but preferably at least one of them needs to be faster than the enemy's 2nd and 3rd monster.

The enemy Sherezar will go first and either use Grandmaster's Scroll, Curse of Decay or the Random Debuff.

If he uses Grandmaster's Scroll you can deactivate cooldowns with Bo Tai or Copperbeard and then take over with your artifacts. If he does anything to deny Bo Tai or Coppebeard it doesn't matter much, because you still will have your artifacts to take over.

I tend to beat Sherezar defences with Bo Tai, Timerion and Talos. If I do not, it usually is because of the monsters Sherezar is paired with.
