the tierlist depends on item rotations and rule rotations, and even despite that I find the tierlist far from the truth

At least someone who doesn't put Blocker on C... but Enidi on C and i don't agree again. Sure Enidi is hard to play, but if you put him together with Blocker and some low cost heroes like Kamaitachi/Reinhardt/Niels/Bunu Shan while having Invoker trait (+ Isolated Island on Top) that becomes the strongest combo possible around the time you unlock all heroes. (At that time you should have mostly 0-1 cost tactic cards) There no need to even fight anymore, Enidi kills all enemies on 1st deployment phase (or at least 4) - and all enemies on their first and 2nd respawn, if you time your energy. He can awaken Bunu Shan on 1st deployment phase. And with 80+ stacks at around round 25 he is unstoppable. [With 6k Gold advantage by the time the game ends]

Frank S tier... Easy 1v9 with him mid on hardest difficulty
