Day 5
O : 5-0 (23-2)
Go with same tactic. The board is good today. No Ferant tank today. So, 5 win 
.
I do face Ferant twice but he is at wing. It is the same-player defense that I face in 3rd and 5th attack.
In 5th, I have opportunity to see Ferant vs minion. Ferant is only enemy left. Minion can trigger Ferant’s mana cut buff. I found that the Ferant’s mana cut buff will mana cut one 5 first counter attack. The minion hit after that get only counter attack but no mana cut. I think the mana cut is 10% → 8% → 6% → 4% → 2% → 0%(no mana cut). 
I am at about tank 300 after do all attack. The lose in yesterday make me miss a chance to be in the leaderboard 
.
D : 66.6%
Defense get some more lose and go down a bit but still hold strongly in A grade
