I don’t really arrange my war teams (no. 2-5) this way so I’m not sure what advice I could give about that. I usually double or triple up strong color to take out my opponents tank.
You have some good heroes however, and I think a really good all-around rainbow team for your #1 slot would be Melandor, Grimm (quickly get him maxed) Bolttusk, Wu Kong, and Tiburtus…true you have some overlap with 2 ramming pulverizers but you’ll destroy whoever you face. You alternately could throw in Merlin instead as his mana control is quite useful. Another superior grouping would see you swap Tibs for Rigard and Hansel for Melandor giving you a lineup of Hansel, Grimm, BT, Wu, and Rigard…on second glance, I think I like this second team even more than the first…the only thing lacking is a debuffer to take away enemy buffs. But you have plenty of material to work with.
You also could go healer-heavy so you never need to worry and can auto-fight alot and use Melandor, Grimm, BT, Wu, and Rigard. That is also an option I like to use at times when i dont really want to pay attention when farming a higher level.
Although I like Kiril quite a bit, i dont favor Lancelot (I have him maxed and dont care for him) and his special wont ‘stack’ with Kiril which is why i suggest Bolttusk as a replacement (whose special also doesnt stack with Kiril). That, hopefully, explains my reasoning for subbing Grimm for Kiril. Sorry if this didn’t come out as clearly as I would’ve liked…its late and I’m tired. Hope this helps a little. Enjoy your day/night…
