Forum:All-out Attacks + Gladiator Beasts

I was using All-out Attacks in my Gladiator Beast deck, and the parameters of the trap card confused me. For example, I used the effect of G.B. Darius to tag him out for G.B. Laquari. Since he is special summoned during the activation of All-out Attacks, would he get to attack, even during the end of the battle phase (which is when the G.B. effects activates)? And if so, would I be able to continue the tagging out effects of my Gladiator Beasts until a card effect or end game stops me?
