>>53757769The easiest for a noob like you would be Zard.
Originally I was going to say Machamp, but he requires a specific skill lv at melee and must stack early to be a monster. Since your use to hiding behind allies and not leading the charge with Sp-atks then machamp is out.
Lapras/Zacian will eventually get nerfed so starting with those isn't good because they don't make you get better, your just using a strong mon Timi likes, but if you want to use those 2 then go for it.
Zard gives your practice with melee since he has to be close for his auto spams but lets you keep the range playstyle you have with Flamethrower/Fire Blast. So slowly you will adjust to melee/close range but still have range kits to help you play better.
Zards Unite should only be used in team fights as his Unite will stream roll any team fight since the enemy team always scatters when Zard uses its unite.
Wait for the actual team fight to start with Zard, do not use your unite to initiate a team fight.
Items should be Muscle/Scope and last item is up to you between BB/Amp/Weight/Weakness whichever you like more. If you suck with stacking go for weakness but you should try to improve by using weight.
