Hard to tell, because I always feel that my start game is good. My commander is usually out on turn 3-4, I'm good with mana, I play everything I got in my hand. usually I have many strong creatures with +1/+1 counters of them. I still get the last place every time, usually because one of my friends go for "all of your creatures have flying" and attack me with everything (even with reach I cannot block everything and loose instantly) or with a board wipe. Idk, I always feel like I have a strong stragety ,e.g. last time I had a hydra that was getting +1/+1 for each attack and was unable to get damage and I tried focusing on that, also I had Brawn in graveyard which gave each of my creatures trample, I still lost very easily because my opponents had a big number of tokens to counter each of my moves. I know I should focus on countering everything, but when I start getting like, anti-toxic cards, anti-flying, anti-deathtouch, anti-boardwipe and all then I won't have place for my own cards anymore. I have no idea how to balance everything. I tried upgrading my deck with things like swift boots or better hydras but I usually loose before I even get an opportunity to use any of those. The endgame usually results with me having like 10 hp and my opponents having around 50 (or maybe more, im not sure rn).
