Nature vs Nature - I seem to have made a mistake somewhere, but I don't know where

I'd like to share the first battle of my morning today. It was a battle between Nature and Nature.

1. Despite being at a slight disadvantage as the second player, I thought I could win if I had Underbrush Boar in my hand, depending on the early game situation.

2. At this point, even though I was the second player, I was able to completely dominate the board, so I was confident of victory.

3. This is where I may have made a mistake. I was unsure whether to replenish my hand or increase my attacking power, but I chose to replenish my cards. I think my failure to reduce the opponent's units at this point may have been the reason for my defeat.

4. I was very hesitant here as well. I chose to offset my opponent's attack, fearing Thunderstrike.

5. I also learned for the first time that enhanced cards can return to your hand.

6. At this point, the opponent had taken the lead, and I was trying to make a comeback with Oni.

7. I tried to use it as a last resort, but the game was already decided.

I think I needed to push hard in the early game as the opponent was a slow starter. At the point where I overcame the disadvantage of being the second player, I think I could have been more aggressive. It's also tough to have Oni in your hand from the early game, so I'm thinking of reconsidering my composition.
