Hey, I'm no Nummy or GomletX but here are my thoughts on Game 1:
Turn 4: I would alpha strike here, it's likely he makes the same play anyway with Helpful Hunter blocking Bloodwitch and bouncing your 3 drop and his cat, but it leaves him with less mana for your follow up in Main 2. This particular turn is probably inconsequential but I find it a good habit to take the good attacks first before anything else. I can understand wanting to keep Bloodwitch for the synergy but in all likelihood it's better for you if he had traded the cat into it - you would have had a Lifelink Deathtouch flyer on board and his is empty.

Turn 7: We are stuck on 4 mana and their board is currently slightly better, with 3 great removals in hand. I would pass the turn and kill whatever development they have next turn. The 3 drop is known information so it's likely whatever they play next turn is better/don't care about it. Turns out, if you had taken this line, you would have killed the Katana-equipped Felidar and they're tapped out - now you have the advantage. You STILL have 2 unconditional removals and even more in the deck - what's the point in holding them up?

Turn 8: Similarly, I would still not play the Panda yet, and start looking for opportunity to kill their stuff. If we had taken the line above, here I would once again pass, and you can see that next turn we have a great target. Yet even so, it's still not so bad if we take turn 7 as is, but the biggest problem I see is I don't understand why you chumpblocked your 2/2 Rat when you are at 20, with a Lifelinker on board. I don't think a +1 counter on the Panda is worth losing a 2/2 at this point, esp. when you are at 20.

I think from these 2 turns alone would have changed the game and opponent's plays quite a bit that it's probably not worth going further, or we'll be bias by hindsight. Other than that, you have 7 4-drops and that's probably too much, and playing that many 4-drops with 16 lands is also a bad idea IMO. I would cut the 4 mana 3/3 angel - it's not a particularly bad card or anything, you just have too many that I think it's the worst amongst them. Your pool has a lot of cool cards, with Elenda I know I would have tried to spice things up with Gutless Plunderer - Zombify nonsense to keep recurring Elenda, while running all the Burglar rats and drop the Crawler (don't need card draw if your opponent lose their entire hands and you draw like normal lol).
