These are the exact habits that keep players stuck in Bronze and Iron. Fixing even 3 of these will jump your placement immediately.
✓ Do This
Save to 50g for interest income
Commit to a comp by Stage 3
Put 3 items on your main carry
Level up at Stage 3-2 / 4-1
Check opponents' boards before placing
Lock bench units you want to keep
Win carousel by tracking HP order
3-star cheap units before buying expensive ones
Spread units to counter AoE comps
Accept loss streaks — they give bonus gold
✗ Avoid This
Rolling every round "to see what shows up"
Spreading items 1-per-unit instead of stacking
Chasing 5-cost carries at Level 6
Leaving bench full and not selling useless units
Ignoring carousel to fight in place
Never leveling up (staying at Level 4-5 all game)
Pivoting comps at Stage 5 with no gold
Placing your carry front-row "so they attack faster"
Playing the same rigid comp regardless of what you hit
Tilting and giving up after Stage 3 losses
The golden rule: Play flexible. The best TFT players don't force a specific comp — they look at what units they're naturally getting and build the strongest board from those units.
