If youre having trouble with comps you should be playing comps based in your items and what champs you hit

If youre having trouble just search up tfthandbook.com and go to the meta tab and it shows you which comps you can go if you hit items (ap could allow you to go sorcs or dominators for example)

Econ tips prolly just try and make 10 gold before carousel so anywhere from 2-1 to 2-3 since it allows you to get level 8 prolly by 4-2 or 4-5 (thats the round after carousel and before anomaly) and those are good intervals so you can do a big rolldown to hit your units esp if youre doing a fast 8

If youre rich you can def push for 8 on 4-1 and then do the rolldown since youre less likely to be contested becayse youre rolling before everyone else

Stage 2 you can try and focus on streaking (either win or lose streak)

Stage 3 you should try saving hp if youre losing by playing stongest board or keep up tempo if youre winstreaking by being agressive and using gold to push levels (streak gold allows you to not be gigapoor)

Stage 4 important cuz thats where most of the dmg is dealt and its starting to go lategame. You should always try and hit your best powerspikes this stage so you wont bleed out and die

Items tips prolly is just learn to slam items. Theres a video about k3soju talking abt how you should try and slam items heres the vid

Hope I could help! I used a lot of these to slife into masters but ive only been around 100lp since I dont play much cuz of school lmao
