Had a chance to watch the set so I could write some thoughts.
Game 1
So, game one, you ended up in a tough spot in the endgame, but it was still winnable if Xiba drew only 1 Joker. If you had dodged on your last turn, you have a choice between KD to extend your life, or just trying to deal 21 with J++. That would leave them at 7 HP to your 1 for the coinflip.
Game one was lost off being put into Bubble Shield for lots and lots of turns. Xiba won it off the back of 3 Blowfish Spikes, basically. In general, I wouldn’t be too mad at losing a first game against an opponent you’re not familiar with. Your goal should be to try to formulate some sense of their decision making progress, and identify any clear tells.
My take-away from game 1 would be: (1) Xiba doesn’t seem interested in throwing me, (2) I need to conserve J++ and AA for late-game dodges. You also tend to decide to get aggressive too early, imo. Valerie is a mid-range deck: she kind of gets bullied in the early and late game, but she shines in the mid-game. Unless you draw really well, her opening hands tend to be a bunch of garbage. You have to fight the temptation to win sub-optimal combats that don’t benefit you.
Game 2
No throws in the mid/late-game due to REALLY bad draws. This is another reason it’s so important to make sure you are playing for high value in the early game. You went for two throws early that didn’t lead into anything, and spent a 7 looking to draw into normals. Then your deck decided not to deliver any more throws for the rest of the game.
In spite of the most abysmal draws I have ever seen in a game of Yomi, you still managed to bring it to a coinflip. If Xiba had no Joker, you could have thrown into 6J++ for lethal on the last combat. Lessons remain the same. Chalk this loss up to unfortunate draws.
Game 3
No blocks. Jesus. Drop this character, she’s cursed.
Also you throw from KD as soon as you draw another block. Don’t do that. It won you combat, but you lose the block and can’t follow it up with anything or set up for a good cross-up. That happens a bunch more times on subsequent turns. Throw into nothing, no good play on the next turn. Just block. They’re not throwing you often enough that you should stop.
Game 4
Practically no blocking, lots of throwing into no follow-up/set-up.
In the end-game, where you have him at 11 and block up to a big hand, you’re still holding on to 6s when you should probably just power them up for Aces and try to dodge into A or AA to clinch it. You had a guaranteed “do not die” play on the last turn - block with blue-burst to back it up. As you probably realized, clashing Q into AA would have killed you, since you were at 18 - you don’t get to pump moves when they clash.
In general, block more, play from a higher hand, only play to win combats that actually benefit you strategically.
