Well, it somewhat depends on what color tank your alliance is running for wars, or if you guys are running an all one color tank strategy or not. Also, I’m assuming Magni isn’t quite ready to go yet. Once he is, your 5* lineup could be:
For war, I’d put in 4* in place of the 5* that aren’t at 4T yet, since their health stats are lower, but their overall stats are better. Maybe something like:
Although, Kashhrek would be the #1 choice for a 4* tank. Elena is your strongest, but has too low of defense to tank for you. Ideally, I’d want the beefiest hero in defense/health as tank, that either has a fast/crazy effect or that supports their flanks to do the same. Flanks I like the important heroes that are game-changers like Grimm or Proteus, because you definitely want them charging and going off. Or healers (if there isn’t one tanking) to make sure your heroes survive and to possibly buff/dispel. Wings I like fast snipers, that don’t need much to charge, and can pick off the remaining opponents one by one.
If you do decide on a color, it can be a good strategy surrounding the tank with the color that the enemy is weak against (if they stack vs the tank). Ex. If you run a yellow tank, your opponent might stack purples, so in order for them to run out of the colors they need faster, and to make it more difficult in a stack for war, use two purples heroes as flank/wing (as long as they’re not on the same side). Or, if you’re running a red tank, they’ll bring in blues, so flank or wing with greens.
Although, I’d only suggest doing this for war, because for regular defenses, this strategy needs a little more thought put into it in order for it to succeed. Rainbow is the best go-to regular defense, at least until you have a good setup to try something else.
Defense teams aren’t an exact science, so this all might help or it maybe won’t, but hopefully it makes enough sense to have an idea on how to try something else if the suggested doesn’t work for you. & Of course, I’m always here if you have any questions
