Forum:Gladiator Beast Murmillo vs. Heroic Champion - Gandiva vs. War Chariot

Greetings...

I witnessed a particularly complicated exchange during a card battle.

Player 1 attacked with a Gladiator Beast (identity is not important), and then tagged it out. Player 1 special-summons Gladiator Beast Murmillo with the intent of targeting Player 2's Heroic Champion - Gandiva for destruction as per its effect. Player 2 detaches Xyz Material on Heroic Champion - Gandiva in order to negate Murmillo's Special Summon. Player 1 uses Gladiator Beast War Chariot to negate the effect and destroy the monster.

Two questions: 1) Is this legal with all the effects involved, and how would it resolve if legal? 2) If War Chariot destroys Heroic Champion - Gandiva, does that mean Murmillo must choose another target? Zorpheus (talk • contribs) 23:48, February 12, 2014 (UTC)
