League of Legends TCG cards focus on spell timing

In the TCG card game "Rune Battlefield", the rules for the timing of using focused spells are as follows:

The focus spell can only be used during the player's own turn and not during the battle. In the new version, the default speed of spells is "focus", which means that the designer has removed the keyword "focus" as it is now the default. However, this did not change the actual speed of the spells; it merely altered the way they were described for the sake of clarity.

The effect of the focus spell can be played at any time, including before calculating other spells or abilities. This feature makes the focused spell very useful when players need to respond quickly to battlefield changes or interrupt the opponent's actions. For example, when the opponent is about to launch a powerful attack, players can use the focus spell to weaken the opponent's attack power or enhance their own defense, thereby defusing the crisis.
