You probably lack match sharpness. Just play a little more to get it back.
Deck is okay, but i won't put Jeena and Flora in a same deck.
Yeah I know, this week just happens to be GHEIST/Roots heavy
This same thing happened to me I hadn't played in over a year when i came back i forgot everything what helped me is i played in solo and also against kate also playing in elo and tourney helps .
but solo brought my memory back of the things i forgot .
I don't think there is any reason that Jeena and Flora cannot be in the same deck, especially in such a high power deck like yours. Maybe it's just my opinion, but for this week I will choose Nakata instead of Heitachi and upgrade Treeman to Rico/Noodile.
Yah jeena and flora are both great... use both. only time i see a slight problem would be jeena flora treeman kusuri, but you can still work around that .
dont like yoshida, especially with so many SoAs around. I'd honestly rather use kuei. or if you are rich maybe try kerozinn cr.
