Arena battle , Win battle during the enemies turn (Resolved)

[Karfraz]

I have been playing this game for awhile.this objective still confuses me. I’ve won battles when the enemy’s as won the coin toss. But I don’t get the win. By accident I have won maybe one battle. But I can’t remember what I did.
HELP. What does this mean

@karfraz You have to knock down the banner using a “poison” attack.

The damage from the poisons of Rogues, Druid and Rainbird are applied in the opponents turn. So the final damage to the banner must be caused by the “poison” damage, from any or all of these bird classes.
