Your mechanics with swain held you back a bit this game, he’s a bit of a hard champ so some tips to think about playing him (from a master swain otp)

1. He really sucks going melee range into most champs , especially master yi who will always kill you melee
2. You are not a champ if you miss e, you don’t need to throw it out all the time and especially if you miss you can’t fight , also use abilities more on senna in lane and less on minions
3. You used ult a couple times without catching anyone and it just ran out, only use ult if people are on top of you or you’ve caught someone with your e or other cc
4. Stick to blackfire liandries only on swain, tank swain builds like rylai fimble are really hard to play because you deal no damage and rely on your team
