Talk:Dimensional Demonic Dragon, Ladis the Tyrant/@comment-26021817-20150119071135/@comment-839017-20150119073458

Allow me to explain what it means.

Say that Ladis is attacked by Armored Dragon, Cuelebre, and you have two cards in your hand at the moment: Bold Dragon, and a Wild Dragon card. You decide you want to Counterattack it to soften it up for next turn, so you cast Bold Dragon to boost Ladis to 9000 defense. In response however, the opponent casts The Wydar Sarkal on Cuelebre, boosting its attack to 10000, so it passes and hits Ladis. Because in Buddyfight a chain can only ever be 2 cards long, with one card belonging to each player, and each player is only allowed to activate a single Counter ability in battle, you cannot activate the natural ability of Ladis at this point, so it is outright destroyed and you can't do anything about it.

The other outcome of this is you save Bold Dragon, and instead just use Ladis' own ability to prevent it from leaving the field by paying the 2 Life and discarding a Wild Dragon. What the rules you are reading mean are that you can't use the ability of Ladis here to save its own skin if you casted another Counter card in the same battle. If you decide to just activate the ability to keep Ladis around after the battle, its a completely legal move.
