Ranvir isn’t even an option vs blue if you have Tarlak. And you need a hero that decreases defense even if it’s off-color.
100% mana (mostly for Isarnia)
25% mana/(Random healing potion)
I haven’t gotten my Telluria up but I feel she isn’t a great fit. Minions always slow it down a tad, her attack is low and the heal over time has conflicts with Tarlak. And you do not want to run Ranvir and Telluria instead. Others would have to chime in how she fares, won’t make my team when maxed either.
Blue and red titans are my favorite ones but you are missing other special heroes. You should be good for 80-100k sometimes if bringing Tornados, but can’t do that all the time.
