Galio should be placed alone in the frontline
For the majority of Teamfight Tactics players, placing tank units in a line at the front is the best way to ensure durability. However, in Galio’s case, you should only position this unit alone in the front line. If you still arrange it in the usual way, Galio will not be able to provoke the maximum number of enemy units, inadvertently reducing the effectiveness of this unit.

Moreover, in some cases, arranging tank champions in a line with Galio on the team can inadvertently hinder your carry. When Galio uses his skill, this unit will provoke and force enemy champions to attack him. At that time, the opposing unit will try to reach Galio’s position to attack him. If you have multiple units blocking the enemy champions, that unit will inadvertently take a detour and reach the backline of your formation. Once the provocation ends, the opposing unit will turn to attack your carry.
Do not place Lucian in the corner of the battlefield unless facing Assassins
As a ranged carry champion, Lucian has low defensive stats and is easy to take down. Therefore, players often tend to place this piece in the corner to ensure maximum safety for Lucian. The weakness of this setup is that it sometimes causes Lucian to cast his skill, Purge, towards the opponent’s carry. This can lead to wasted damage and might cause players to lose in a regrettable manner.

To solve this issue, the top players at the TFT World Championship: Reckoning have devised a method of positioning Lucian in the middle of the bottom row. This arrangement allows Lucian to still identify the opponent’s unit in the furthest cell and cast his skill there, even if the opponent switches positions with their carry. Of course, this arrangement will be most effective when your opponent does not use Assassins. If you are up against strong Assassin players, placing Lucian in the corner of the battlefield is still a good choice.
Draven needs to be placed in the front line
One of Draven’s weaknesses compared to other carries is that this unit relies entirely on auto-attacks to deal damage. However, Draven’s attack range is shorter than other units in the same position (3 cells), making him prone to wasting time moving and missing out on damage. Therefore, players at the TFT World Championship: Reckoning often place Draven in the front line to save this unit’s movement time.

Not stopping there, this arrangement also helps Draven avoid being focused down by Lucian or Vel’Koz. However, to apply this setup, you need to have excellent observation skills of the opponent and be able to reposition your formation very well. You should place Draven in the outermost cell of the front row, away from the enemy’s sources of damage and crowd control. This is an important skill that players should practice regularly in every match.
