I think in your first match, your Squirtle was too grabby, and left itself open too many times.
I would also like to compliment SODA's great counterplaying in the first match. Very nice use of Lucas. Your Ivysaur had several times that it could have hit with a critical bullet seed, and the grabs may have made more sense from Ivy than Squirtle.
Your Charizard, in the first match, while I must compliment your use of Fly, is still needing a bit of work. Your technique is nice, but you leave yourself open a lot.
Your second match showed improvement in your characters, although I do wish to warn you not to try to return with Withdraw- you CAN be knocked away to your death, even if withdraw can cancel.
Your Ivysaur needs a bit of work, although the poisonpowder was nice. Again, the bullet seed and the throws would improve it.
Your Charizard this time was very much improved, but left huge holes in its defenses. If Lucas was slightly better, I feel you probably would have lost the match quicker.
However, amazing comeback.
I'd also like to compliment SODA's improvement, which is visible in this match.
Third match, you started off with Squirtle...again, and I noticed you tried to recover with Withdraw...a bad move for recovery. Solid damaging with Squirtle, although you got greedy in the end.
Ivysaur got better...but more predictable. Might want to try mixing up your moves some.
Your Charizard was barely out save for a cameo kill. I think that Charizard, while slower than your opponent, still could have gotten some nice hits in before retreating.
That said, very good playing all three times to both you and SODA.
(Although there is nothing wrong with using it).
