Action during Battling:

4. Damage Step: Compare the power of the attacking card with the power of the attacked card. If the power of the attacking card is greater than or equal to the power of the attacked card, you will win the battle and the result will depend on the attacked card.
(If you attack your opponent's Leader, inflict 1 damage on the Leader who lost the battle. If attacking a Character, KO the character who lost the battle and put it in the trash. If the attacking card loses, nothing happens.)
When your leader is damaged, add 1 card from your life to your hand.
At this moment, if the card has a [Trigger] effect, you can reveal the card and activate the [Trigger] effect.
Also, if the leader is damaged and there's no more life cards for him, that player loses the game.
Hi all,
Can you please indicate if you can use a counter effect to boost a character attacks to avoid a character being trashef due to an effect from an other character on play or an event? (example : trash up to one of your opponent’s character with an attack of 6000 or less. Can I use a counter from my hand to boost the attack and go up to 7000 and avoid having my character trashef?)
