when ur opponent uses kaiser coliseum u cant have more monsters on the field than him except when he/she activates the card effect (but say ur opponent has 2 monsters and u have 3 then if one dies u cant replace it) here this is information about kaiser coliseum from yugioh-card.com:





"Your opponent can still Flip Summon a monster.





If there are already more monsters on your opponent's side of the field when you activate "Kaiser Colosseum", nothing happens to your opponent's monsters but your opponent cannot Summon any more. Also, if the number of monsters controlled by "Kaiser Colosseum"'s controller is reduced, the opponent does not have to remove any of his monsters.





Your opponent cannot use "Monster Reborn", "Scapegoat", etc. while "Kaiser Colosseum" prevents him from placing new monsters. However, your opponent CAN use "Change of Heart", "Snatch Steal", etc.





If all monsters of "Kaiser Colosseum"'s controller are destroyed, "Kaiser Colosseum"'s effect no longer functions until that player has at least 1 monster again (when the effect re-activates).





If the player who controls "Kaiser Colosseum" has his only monster taken by the opponent with "Change of Heart", then the opponent can place more monsters because "Kaiser Colosseum"'s effect is no longer active until the player has at least 1 monster again.





When "Kaiser Colosseum" is active, and "Cyber Jar" is activated, if your opponent would control more monsters than you, your opponent has to destroy monsters equal to the difference; the excess monsters are never actually Summoned and instead are sent from the Deck to the Graveyard (so "Witch of the Black Forest" does not get its effect, etc.). So the monsters are destroyed after they are picked up, but before any monsters are Special Summoned for the effect of "Cyber Jar".





While you have "Kaiser Colosseum" on the field, your opponent can Tribute Summon, if after the Summon they will control less or an equal number of monsters as you do."





oh be the way if ur opponent ever uses kaiser colosseum against u try to destroy all his monsters then summon as many as urs, thats wat i usually do.
Reply:No the monsters you already have on the field are not affected.So if you have more monsters than your oppenent when the card is played you just can't summon any more until he has more than you.I have also found a way around this.You can summon tribute monsters (monsters that need sacrifice) so the number of monsters you have will be the same or less.
