can someone explain how does chains work really
ex:

a player summons frost monarh with his effect he desides to destroy a monster or a card can i use that same card in the chain or not???
also a players mystical swordsman attacks a face down card i use ceasefire is he going to destroy my monster

please help the chains are so difficult to understand :confused: :confused:

Ok first of Mobius the Frost Monarch can only destroy magic/trap cards.... now after the controller of Mobius has chosen which cards to destroy YES you can chain those cards (if they can be chained) to his effect.....
If you chain Ceasfire to Mystic Swordsman's ATTACK then the monster won't be destroyed by Mystic's effect..........

Any Magic or Trap card targeted by Mobius's effect can be chained. Only Quickplay Magic cards can be chained just so you know.

Ceasefire would flip the monster face-up before the attack, so Mystic Swordsman would still atack the mon, but not destroy it with his effect. It might destroy the monster anymore if its def is less the Swordsman's atk.

To help you understand Chains more this may help.

The instruction booklets in the Structures explain this well, as do the Website, www.yugioh-card.com, so to learn more research those resources. But in regards to your answer, Traps are spell speed 2, so they can be chained to pretty much any spell card and monster effect of Spell Speed 1. Mobius's effect is Spell Speed 1 (I think it's an ignition effect?) so it can be chained to by a Trap or Quick Play Spell (Spell Spped 2).

Mystic Swordsman is attacking. You don't chain to an attack. I think what you were doing was activating Ceasfire after your opponent declared an attack. This is legal. Flip up the monsters and do the damage, then now we go to damage calculation, and Mysic Swordsman would have to do damage calculation because the monster it is attacking is not face down.
