Kunhen is one of the best centers, but he is slow, vivica as well, beside kunhen you have to have some fast snipers, you just can’t put them together, it will be to easy to feed them both with usless tiles, but in corner, while opponent fighting against kunhen, if vivica got mana it’s almoust 100 %, victory.
And of course thorn will be beter, five star is five star
