So I got this lil’ team here, for raid defence ;
Been pretty solid so far, and is floating in and out of the very bottom of Diamond, which is pretty nice 
Been wondering though, since I seem to be drowning in 5* Purples, should I swap out any of the above with the following Purples instead? ;
Ursena
Sargasso
Sabina w/ max emblems
Quintus (with/without costume)
Sartana
Clarissa
Grimble
Domitia (with/without costume)
Obakan
I’d love to hear some thoughts on this. 
Mono is not a good option IMO, but if it should for fun, with purple mono, at least bring Ursena as tank, and also even better if there is Mok-Arr in that defense.
I’m with Jinbatsu…but when you like putting mono in def then Ursena as Tank and Clarissa as Flank are a must have there.
Why would you wanna do this? Most decent opponents will just bring 3 or more yellows and have their way with an all purple defence.
To answer all, I’m doing this for fun and I’m not really interested in climbing / getting more cups, sorry for not making this known from the getgo Thanks all for the advice so far though, and I will definitely look into bringing Ursena onto the team!
Mono purple or any other color for defense spells B - A - D. This is mainly due to the fact that leveling the supporting troops is hard enough by reason that it is food extensive and that feeder troops are hard to come by, apart from the attacking player bringing a stack of yellow heroes, which would easily kill most defending purple as it may not be supported by a high-level troops.
Place Ursena as tank, preferably maxed and emblemed and flank her with a strong yellow. Rainbow defense is still lauded as the best defense.
It is bad, but the troops are a secondary (but valid) reason.
Attackers get color effects. Defenders don’t. Defensive attacks are considered colorless. So that purple hero swiping at your yellow hero is the same as if it attacked a blue.
OP is doing this for fun, and that’s fine. And sometimes it makes sense to stack because you’re weak on a color or synergy of specials, but in general, just as you said - rainbow is king for defense.
Freya has no place in there being unmaxed. You really need one yellow in there to keep the enemy honest. Never recommend mono defense.
Oh, they do. It only takes one HOTM and the element link applies to all defending heroes. Try placing all purple HOTMs with element link and you will see those mini icons sprouting on all of them. That is color effect, too. Maybe what you are inferring at is the stack of attack stats.
All i am trying to say is that the OP would have more fun seeing more defensive success at the Watchtower with rainbow defense than the silly monopurple defense.
Have fun! Keep the game interesting. My only suggestion would be to look at Ursena, Clarissa or custom Domitia, to add to the line up. Ursena is very strong. A emblemed Clarissa should be a beast (Telluria is using my Paladin emblems). Custom Domitia has been a nice piece in some of my raid teams.
I agree with @Chadmo. Level Freya to take full advantage of her specials.
Please keep me posted. I may follow your lead! 
Sartana (because panther has an emblem conflict with killhare) - domitia (no costume for the yellow defense buff) - Ursena - Clarissa - Killhare
That set up should be fun 
This defense could be improved…with a dozen more Tabards. 
However, to my surprise even leaving in this team in it still keeps me at 2300+ cups.
Some probably think it’s a stylish way of cup dropping? I dunno, but it was a nice break from having to revenge all the Telluria +18’s.
By color effects I meant increased/decreased damage based on color for normal attacks.
Not sure how you thought I meant anything about element link.
There. I have emphasized what you said and my response to what you said. You mentioned COLOR effect not effecting on defense. I mentioned Element Link. I was even inferring that you may have intended to mean stacking attack stats.
